Hi-TRACE - Industrial process optimisation through improved metrology of thermophysical properties

Many industries use materials at very high temperatures (up to 3000°C) and in harsh conditions such as shuttle re-entry, gas turbines, aircraft engines and processing of refractory materials. Therefore, accurate knowledge of the thermophysical properties of such materials is needed to ensure optimised processes and to develop new materials. However, for solid materials currently the traceability of these measurements is only possible for temperatures below 1500 °C for emissivity and specific heat, and below 2000 °C for thermal diffusivity. Proposals in response to this SRT should therefore, develop new methods and infrastructure to extend traceability of measurements of spectral emissivity, specific heat and thermal conductivity, temperature of fusion and mechanical adhesion to temperatures up to 3000°C.
