TC11 UPDATE 2012

ESIS TC11 (HTMTC) committee meetings
- main committee meeting on 15th May 2012 at EDF, Gloucester, Barnwood, UK,
- temperature measurement working group meeting on 17th July 2012 at CCPI, Sheffield-Rotherham, UK

ESIS TC11 (HTMTC) Workshop activities
TMF-Workshop 2011
The editing of the papers to be published in the International Journal of Fatigue is virtual complete and it is planned that the special issue would be issued later in the year. The editing of the papers to be published in the special issue of Materials at High Temperatures is close to be finished. The Information about the TMF Workshop 2005 has been transferred to the website www.tmf-workshop.bam.de. It will be linked with the HTMTC Website, too. The CoP for strain controlled TMF testing, originally published in 2006, is beside the standard ISO 12111 one of the most important TMF testing procedure documents worldwide. Thus it has been published again on the TMF-Workshop website because it has been removed from the website at JRC, Petten, NL.

Workshops on Quality Assurance Issues for High Temperature Testing
The 1st workshop took place on 15-16 May 2012 at EDF, Gloucester, Barnwood, UK. 38 participants attended the Workshop. The program contained numerous excellent contributions from experts in the area of quality assurance acquired from institutes, industry and from ESIS TC11 (HTMTC).

It is intended to hold the 2nd Workshop at INCOTEST, Hereford, UK on 13th-14th November 2012.

Joint workshop on Accelerated Testing Methods together with IOM3 High Temperature Materials Committee (HTMC)
Dr Barnard proposed that a meeting on ‘Accelerated Testing Methods’ would be a viable venture. The meeting will probably take the format of a 1½ day meeting in spring 2013 possible at the Riverside Centre (Pride Park) Derby. The meeting will comprise three ½ day sessions: a) Testing Methodology , organised by the HTMTC, b) Data for Lifing organised by Mike Spindler, EDF and c) Metallurgical methods, organised by the IOM HTMC. The Testing Methodology session could include acceleration by stress, temperature & environment. The automotive sector use truncated wave forms and ‘rainfall’ analysis, mostly in the non-creep regime. P Barnard agreed to pursue the matter and try to confirm that the dates would dovetail in with Wednesday 22nd May 2013, the proposed date of the HTMTC Meeting.

Workshop on Non-Contact High Temperature Strain Measurement
Dr. Klingelhöffer contacted Prof Dr Nikbin and Dr Catrin Davies of IC, London, to hold a workshop non-contacting strain measurement. This topic should contain Digital Image Correlation techniques and non-contact extensometry, too. It is planned to hold the workshop in autumn 2013 at IC, London.

ESIS TC11 (HTMTC) working party activities

Testing in Controlled Environments WG: (Convenor: O O’Grady)
The Draft ‘Scope & Objectives’ had been prepared. It was agreed that there was merit in pursuing the subject provided the Scope was widened to encompass ‘Non-Standard Testing Techniques’ Members of the Working Group would include Owen O’Grady, Phil Jones and Mike Lynch. The Convenor agreed to revise the Scope.

Temperature Measurement for HT Testing Working Group (Convenor M S Loveday) Mr Loveday reported that he had relocated and re-plotted the data that he had been recorded approximately 15 years ago at NPL showing the results of drift measurements on Type R Pt-Pt/Rh thermocouples after long term creep tests. The implications of thermocouple drift will be incorporated into the Draft CoP. It was also reported the results of further calibrations of thermocouples had been forwarded to Andrew Wisbey, SERCO, who is co-ordinating the Thermocouple Calibration Inter-comparison exercise. Furthermore some additions have been made to the Bibliography for the draft CoP.

Code of practice for stress/load controlled TMF testing
Dr Stephen Brookes (Rolls-Royce-MTOC, Dahlewitz, D) gave a presentation based upon the in house testing procedure developed at the RR-MTOC. The stress controlled TMF tests performed at MTOC are intricate and incorporate a combination of temperature-loading phases replicating the service cycle of a component. The Committee supported the proposal that there was a need for a CoP covering Stress Controlled TMF testing and Dr Brookes offered to provide a document which could provide the basis of a CoP which could be circulated to other interested parties who could form a Working Group. Mr Brooks, NPL, expressed interest and it is thought that representative from Exova, SERCO, Risley, together some groups in Germany would wish to participate. Dr Brookes agreed to circulate a draft document for circulation to interested parties.

The following are extracts from the outgoing Chairman’s Report, prepared by Mr Paul McCarthy, which gives a summary of TC11 activities during 2009:

1. Introduction
The Committee has continued to be active throughout the past year. Two meetings have been held, working group activity continues and plans developed for future activities / meetings of the committee.
Further information about the HTMTC may be found on the web-site at www.htmtc.com

2. General Activities

2.1 European Structural Integrity Society
The High Temperature Mechanical Testing Committee (HTMTC) operates as Technical Committee 11 (TC11) of ESIS, whilst retaining its status as a UK Charity and a Company Limited by Guarantee. Contact with ESIS has continued and the activities of the HTMTC have been published in the ESIS Newsletter.

2.2 Conferences and Seminars
During 2009-10 no formal conferences or seminars were held.
Committee effort during 2009-10 has focussed upon events for the next two years. The first of these will be a meeting on High Temperature Mechanical Testing in Controlled Environments, co-ordinated by Phil Jones and Mike Lynch, to be held on 20th and 21st April 2010. The steering group, plus organisational support staff from Serco Assurance, have put significant effort into its organisation and the success of this workshop will be due to their hard work. The second event, co-ordinated by Dr. Hellmuth Klingelhöffer, is the 2nd International Workshop on Thermo-Mechanical Fatigue, to be held on 12th and 13th May 2011, at BAM Federal Institute for Materials Research and Testing, Berlin,Germany,see www.tmf-workshop.bam.de A third event, addressing Quality Assurance Issues for High Temperature Testing, is planned for later in 2011.
In addition to the above, individual members have continued to participate in several very successful testing related meetings outside the HTMTC umbrella, and have been heavily involved in the development of new ISO Standards on mechanical testing.

2.3 Publications
Publications by the Committee during the year have been limited during 2009/10; no activities being undertaken under the HTMTC umbrella have progressed to the publication stage.

2.4 Working Groups During the year the following Working Group activity has taken place:

  • Although the Testing of Weldments Working Group, under the chairmanship of Prof. B. Dogan, has not met during the past year, its Code of Practice on Testing of Weldments is making progress towards becoming an ISO Standard. The subject has also been taken up by International Institute of Welding (IIW) Select Committee Standards (SC STAND).
  • The Temperature Measurement Working Group, under the Chairmanship of Mr Malcolm Loveday, continues to explore novel temperature measurement techniques, such as an in-situ calibration method exploiting phase changes to define thermal fixed points. Work on developing a code of practice continues.
  • The Miniature Testing group is maintaining a watching brief on developments in this field and, when the situation is appropriate, will expand its activities.
  • The Crack Initiation Group, under the chairmanship of Prof Kamran Nikbin (Imperial College), has progressed its work in this area within ASTM, VAMAS and the European Project CRETE:
    a) The collaboration in VAMAS TWA25- Component Testing – has produced a final version of the ISO/TTA* 5 - ‘Code of Practice for Creep/Fatigue testing of Cracked Components’.
    b) VAMAS TWA31 –Weldments - is continuing to discuss crack initiation in welds and HAZ. A small meeting was held in conjunction with Welds 2009, in Florida in June 2009.
    c) The EU project ‘CREETE’ has been completed and the results are incorporated in to the ISO/TTA 5.

 2.5 Related Activities

  • Members of the committee have contributed to a number of national, European and International Standards committees during the year. Work has now come to fruition on the preparation of a new ISO Standard on TMF Testing (Dr. Klingelhöffer, Dr Hähner & Mr Loveday) and the revision of the ISO & ECISS Tensile Testing Standards (Dr. Klingelhöffer, Mr Loveday & Dr Peter Morris). ISO 204 – Creep Testing – is now published has involved both Mr. Loveday and Mr. McCarthy; and revision of the ISO Extensometer verification standard is proceeding (Mr McCarthy, Mr Loveday, Mr McEnteggart).
  • The German standard committee on “fatigue testing” has been re-established after 15 years inactivity and has been mirrored the ISO TC164 SC5 committee which contains 14 working groups with related fatigue standards. The committee intends to be active in all working groups of ISO TC164 SC5. Furthermore a member of the German fatigue standard committee activated Austria to be active in the fatigue standard regime, too. Now Austria has also voting rights on the ISO scale. It can be summarized that four European countries are active in the fatigue standard regime but according to European regulations five countries are needed that Europe is able to start standardization projects in the fatigue regime. But we are confident that a fifth European country will be found.

3. Main Committee Meetings

The main committee met twice during 2009/10. The first meeting was the AGM held on Friday 24th April 2009 at EMPA, Dubendorf, Switzerland; the second was at Doosan Babcock, Tipton, UK on Tuesday, 27th October 2009. The minutes and ancillary papers from these meetings have been circulated to all members.

4. Conclusion

The Committee continues to operate as an effective Thematic Network. In-depth technical networking has continued, resulting in the development of new testing techniques, or contributing to the preparation of European & ISO Standards. As in 2008/9, the latter item has involved significant effort from members of the committee over the past year, fulfilling our remit to maintain testing methods for the high temperature testing field at a “state of the art” level. In addition, codes of practice issued by the committee have been kept under review and will, when necessary, be revised to reflect developments in technology and operational practice. Our aim for the future, as a committee, continues to be focussed on the generation of other such codes of practice, benefiting both the European and global testing communities. The main activity during the year focussed on planning major Workshops/ Seminars to be held in 2010 & 2011.


The AGM was followed by a two day Workshop on ‘High Temperature Mechanical Testing in Controlled Environments’ which was attended by over 50 people despite a considerable number of people unable to attend due to flight cancellations due to volcanic ash from Iceland.Further details may be found on the HTMTC Website: www.htmtc.com

TC11 UPDATE 2008

 

COMMITTEE REPORT 2007 / 2008

Presented at the AGM held at the IE-JRC Petten, NL on Friday, 18th April 2008.

INTRODUCTION
The Committee has continued to be active throughout the past year with members organising a well attended and timely Seminar on ‘Mechanical Testing for Next Generation Nuclear Systems’. In addition effort was expended on a) preparing  the publication of papers presented at Seminars held in previous years, b) through working group activity, c)  representation on  International Standards Committees and d) other related activities as detailed below.
Further information about the HTMTC, including the full minutes of the AGM, may be found on the HTMTC web-site at www.htmtc.com.

 

FUTURE MEETINGS
•    54th  Committee Meeting- an AD Hoc Meeting will be held to cover urgent business will  be held on Monday 10th November 2008 at British Energy, Barnwood, Gloucester, UK, proceeded by Working Groups.
•    55th  Committee Meeting- (AGM)  Friday 24th April 2009 at EMPA, Dűbendorf, Switzerland. [ to be held in conjunction with the ECCC Conference ‘Creep & Fracture In H T Components-design & Life Assessment’,   Tuesday-Thursday, 21st _  23rd April 2009 ]

 

GENERAL ACTIVITIES
European Structural Integrity Society (ESIS)
The High Temperature Mechanical Testing Committee (HTMTC) operates as Technical Committee 11 (TC11)  of  ESIS, whilst retaining its status as a UK Charity and a Company Limited by Guarantee. 
The Vice Chairman, Dr Hellmuth Klinglehoffer represented  the HTMTC at the ESIS Council Meeting. 

 

Conferences and Seminars
The highlight of the year was the seminar held at the JRC Petten in April 2008 on ‘Mechanical Testing for Next Generation Nuclear Systems’ organised by Peter Haehner, Roger Hurst and Nigel Taylor. This was a well attended and timely meeting and will probably lead to further activity in this area. The power point presentations will shortly be made available to the delegates who attended the meeting.
Because HTMTC organised two meetings during 2005-2006 considerable activity during the past year has focussed on the publication of the proceedings of Welds 2005 held in Hamburg in 8-9th September 2005 and the High Temperature Thermo-Mechanical Fatigue held at BAM, Berlin, Germany 22nd -23rd September 2005.
In addition individual members have continued to participate in several very successful meetings outside the HTMTC umbrella, and have been heavily involved in the development of new ISO Standards on mechanical testing.

 

Recent Publications
a)    The Proceedings of ‘Welds 2005’  held in GKSS in Geesthacht (Hamburg), Germany on 8-9 September 2005 organised by Prof Bilal  Dogan have now been published:  the peer reviewed papers presented at the conference, are in the journals Materials at High Temperatures-, Vol.23, No.3/4, 2006; Engineering Fracture Mechanics-Elsevier, Vol.74, 2007 & in  Int. Journal of Pressure Vessels and Piping-Elsevier, Vol.83, 2006.
b)    The papers presented at the International Seminar on Thermomechanical Fatigue held at BAM, Berlin, Germany in September 2005 have now been published in  ‘International Journal of  Fatigue:  High Temperature Thermo-mechanical  Fatigue: Testing Methodology, Interpretation of Data and Applications ‘ Guest Editors: P.Hähner, H. Klingelhöffer, T. Beck, M. S. Loveday, C. Rinaldi.   Vol 30, No 2.  209-403, February 2008. ISBN 0142-1123.
c)    ‘Measurement of Creep Strain: a) The influence of Order-Disorder Transformations in Ni-Cr-base alloys and b) A Code of Practice for the Use of Ni-base alloy Extensometers.’  Malcolm S Loveday and Thomas B Gibbons. Materials at High Temperatures, 24 (2),113-118, July 2007.
   

Working Groups

During the year the following Working Group activity has taken place: 

•    Although the Testing of  Weldments  Working Group, under the  chairmanship of  Prof. B. Dogan had not met during the past year,  the Code of  Practice on Testing of Weldments has progressed towards becoming an ISO Standard. The subject had been taken up by International Institute of Welding (IIW) Select Committee Standards (SC STAND).
•    In addition the VAMAS Technical Committees TWA 31 is running a round robin testing welded specimens in collaboration with the Weldment Working Group. This activity will provide input, such as residual stresses in weldments, for revision of the future ISO standard.
•    The Temperature Measurement Working Group, under the Chairmanship of Mr Malcolm Loveday, expended considerable effort into the development of a programme to assess the feasibility of developing an in-situ calibration method exploiting phase changes to define thermal fixed points. Although funding had been secured from the UK Government, unfortunately insufficient companies were willing to provide the 10% supporting income by contributing £3k each towards the project and thus the project was cancelled.  However the concepts embodied in the proposal are sound and it is hoped that it could be resuscitated at some time in the future.
•    Although the last meeting of Crack Initiation Working Group was prior to the 2006 AGM  Prof Kamran Nikbin (Imperial College) has progressed the work  in the area within ASTM, VAMAS and the European Project CRETE:
a)    The collaboration in VAMAS TWA25- Component Testing  a final version of the ISO/TTA* 5  - ‘Code of Practice for Creep/Fatigue testing of Cracked Components’ had been produced.
b)    VAMAS TWA31 -Weldments is continuing to discuss crack initiation in welds and HAZ. 
c)    The EU project ‘CREETE’ has been completed and the results are incorporated in to the ISO/TTA 5 
d)    ASTM E1457 – ‘Measurement of creep crack growth times in metals’  was re-issued in 2007 and updated to account for crack initiation. For the current version please visit the ASTM web site.

   

Related Activities
•    Members of the committee have contributed to a number of national, European and International Standards committees during the year. Work continues on the the preparation of a new ISO Standard on TMF Testing (Dr. Klingelhöffer, Dr Hähner & Mr Loveday) and the revision of the ISO & ECISS Tensile Testing Standards (Dr. Klingelhöffer, Mr Loveday & Dr Peter Morris).  The completion of the technical elements of the revision of ISO204 – Creep testing – has involved both Mr. Loveday and Mr. McCarthy; and revision of the ISO Extensometer verification standard is proceeding (Mr McCarthy, Mr Loveday, Mr McEnteggart).
•    The activities of the HTMTC were publicised at The Malcolm McLean Memorial Symposium held in London on 19th - 20th  April 2007at imperial College which was attended by the Secretary, Mr Loveday,  who also presented a paper on ‘Creep, Alignment & Standards’

Main Committee Meetings
The main committee met once during 2007/8 at the AGM held on Wednesday 18th April 2007 at Imperial College, London.  The minutes and ancillary papers from these meetings have been circulated to all members and are available on the HTMTC website.

CONCLUSION
The Committee continues to operate as an effective Thematic Network.  In-depth technical networking has continued, resulting in the development of new testing techniques, or contributing to the preparation of European & ISO Standards.   Over the past year the latter item has involved significant effort from members of the committee, fulfilling our remit to maintain testing methods for the high temperature testing field at a “state of the art” level.  In addition, codes of practice issued by the committee have been kept under review and, when necessary, revised to reflect developments in technology and operational practice. Our aim for the future, as a committee, should continue to be focussed on the generation of other such codes of practice, benefiting both the European and global testing communities.

TREASURER'S REPORT 

The treasurer, Mr Howard Burt, tabled copies of the annual accounts. The expenditure last year was £4,518 (£1,212) and the income was £9,582 (£138)—(The figures for 2004 are shown in brackets), resulting in a net gain for the year of £5,064 (-£1074). It was noted that the main  income was provided by the TMF Workshop held in September 2005 together with the profit from the Data Generation meeting held in December 2004.The main expenditure was associated with the expenses of the TMF Workshop, travel expenses for Prof Carpinteri (President of ESIS), to attend the Welds 2005 meeting and Secretarial services. It was noted that further expenses from the TMF Workshop will be incurred when the Proceedings are published.
Adoption of the accounts, subject to approval by the independent examiner, was proposed by Prof R Hurst and seconded by Dr K Nikbin and accepted nem con. Four copies of the full accounts signed by the Examiner, Treasurer, Chairman & Vice Chairman will be forwarded to the Secretary for submission to Charities House as soon as possible.  
It was reported that Barclays Bank had now insisted that the name of our account be changed from UKHTMTC to HTMTC to align with the registered name at Companies House; this had involved the Chairman & Treasurer in a considerable amount of administrative effort for a bureaucratic nicety.

FUTURE HTMTC SEMINARS
Creep- Fatigue Interaction
The initial flier and call for papers for the IOM3 Meeting ‘High Temperature Fatigue- Influences of Environment & Creep’ had previously been circulated by E-mail by the Secretary. The meeting will be held on Tues / Wed 5th & 6th December 2006 at Carlton House Terrace, London. Although discussions had been held between the HTMTC Chairman and the representatives of the IOM3 Materials Committee [initially Mike Winstone (DTSL, Porton Down) and latterly Mike Henderson (ALSTOM)], it will not be a fully joint meeting since the HTMTC will not benefit by any profits or be responsible for any losses. It is unlikely that the registration fee will be kept low in line with other HTMTC Meetings since the IOM3 staff who are undertaking all the administrative organisation will need to cover their costs. Although the meeting will not specifically focus on testing techniques, nevertheless the meeting will probably be of interest to a number of HTMTC members. The Chairman agreed continue to liaise with Mike Henderson regarding possible speakers etc.
HT Materials Issues in Nuclear Fission and Fusion.
Prof. Roger Hurst confirmed that he and Dr. Peter Hähner, JRC-IE, Petten,
were willing to organise and host  a seminar, possibly next spring/ autumn . The committee were endorsed for the suggestion and the organisers will be asked to map out a provisional programme, and forward it to the Chairman & Secretary for comment  / circulation. Suitable dates need to be identified. There is a likely resurgence of interest in the nuclear option for power generation because of the minimal CO2 emissions and their impact on global warming. This will introduce commensurate challenges for the improvement of testing techniques for the determination of reliable material property data for design of plant and life monitoring. 
Other Future Meetings
The Secretary tabled a list of forthcoming meeting that may be of interest to HTMTC members.  Attention was drawn to several meetings including a) Small Specimen Testing- Methods & Analysis to be held at the IMechE on 22nd May 2006, b) ECF16 –16th European Congress on Fracture to be held in Greece, 3rd – 7th July 2006,c)  The Malcolm McLean Symposium to be held in London on 19th -20th  April 2007 (see Appendix 5) , and d) CREEP 2008 to be held in Bayreuth, Germany on 4th – 9th May 2008.
In addition it was noted that the following meetings were scheduled:  a) the COST Material Conference at Liegè, on 18th – 20th September 2006,  b) ESIA8 on 24th – 25th October 2006 and c) Fatigue 2007 was scheduled to take place at Cambridge on 26th – 28th March 2007.

TC11 UPDATE 2005
 

Under the auspices of ESIS TC11, the High Temperature Mechanical Testing Committee, a successful meeting on Miniaturised Testing Techniques was held on 17th & 18th March 2003, at the National Physical Laboratory, Teddington, UK. The meeting was attended by over 40 delegates, from several different countries, who listened with interest to 20 presentations. It was recognised that demands for smaller components in the Bio-medical, Aerospace, Automotive and General engineering sectors, together with the need for the characterisation of small samples removed from large power plant for remanent life assessment, all pose challenges for scientists and engineers to develop new miniaturised test methods for determining material property data. The meeting brought together research workers from different disciplines to share experiences of developing nano-, micro-, and sub-sized testing techniques for determining material characteristics of metals, ceramics and plastics at ambient and high temperatures. Novel testing methods were discussed as well as the methods used for in-situ testing in Scanning and Transition Electron Microscopes ( SEM & TEM's).

Topic covered included :

  1. Historical Background, Standards & Traceability
  2. Creep & Tensile Testing : Weld Testing & Ring Tests
  3. Small punch test: Compression & Creep
  4. Nano-Indentation
  5. Scanning Micro-Hardness
  6. Miniature Multi Property Apparatus
  7. Miniature & Midi TMF Testing
  8. In-situ TEM & SEM Testing
  9. Nano Stain Measurement
  10. Miniature Compression Testing
  11. Surface Acoustic Wave Techniques
  12. Modulus Measurements
  13. Fracture Toughness / Impact :Drop weight , Miniature CTS & Sub-sized Charpy
  14. Bend Testing : Miniature 4-Point Bend testing
A CD Rom is being compiled and should shortly be available which will contain the majority of the presentations.
