Abstract:

Thermo-mechanical fatigue (TMF) testing plays an increasingly important role in the design of various safety critical components which are exposed to thermal and mechanical loads. At present, however, a standard for TMF testing does not exist, causing a lack of comparability of TMF data. In view of this situation, the European Commission is funding a project, entitled Thermo-Mechanical Fatigue: The Route to Standardization (TMF-Standard). The objectives of the TMF-Standard project are to provide, at the European level, the technical basis that will enable to define in a comprehensive way all testrelated aspects of a standard for strain-controlled TMF, to draft the findings in the form of a Code-of-Practice for TMF testing, to co-ordinate the European input into the ISO Working Group on TMF, and to disseminate the Code-of-Practice among all interested parties with a view to promoting the implementation of a European TMF testing platform consisting of a chain of laboratories measuring TMF properties according to sound metrology principles, thus improving the industrial competitiveness and promoting free trade. In the present paper, the context, scope and content of the TMF-Standard project are described in some detail.

More about this publication?

Materials at High Temperatures serves the needs of those who develop and use materials for high temperature applications. It publishes peer reviewed contributions relating to high temperature applications in the power, chemical, engine, processing and furnace industries.
The effects of high temperatures on corrosion, fatigue, creep, strength and wear in alloys, intermetallics, ceramics, refractories and composites are covered. Papers dealing with aspects of materials usage including modelling of behaviour and life prediction will be particularly welcome. The journal has a policy of emphasizing practical aspects and authors presenting results from research programmes are encouraged to relate these, if possible, to actual or potential applications.
