The project will measure electrical resistivity and thermal property data for a wide range of hardmetals between room temperature and 800°C, in order to investigate the potential for a new quality control technique and characterise non-magnetic materials. Using the range of sample sizes the EPMA also plans to provide data for modelling performance applications where higher temperatures than ambient are experienced.

The project will investigate the relevance of the Wiedemann-Franz relation for hardmetals, evaluate the repeatability and reproducibility of various test methods suitable for measurement of electrical resistivity of hardmetal components, and produce a model of the thermal conductivity and electrical resistivity of hardmetals in 3D. The research will be co-funded by NPL at about the 50% level so the overall cost of the project to the project partners will be €71.5k to be shared by the participants. The project is planned to start at the beginning of 2013.

“After the successful completion of the stiffness of moduli project, we simply asked the involved companies what were their needs in terms of research in development, and resistivity of hardmetals came first,” said Dr Olivier Coube, EPMA technical director. “We have so far received one signed consortium agreement, and 5 other companies have expressed a strong interest. Thus, based on this participation level, we should have a reasonable project cost of around €10,000 per company for an 18 month project.”
