Understanding the thermal properties of metal powders: Characterisation of powders using the Hot Disk technique
The thermal properties of metal powders strongly influence the sintering, final
density, and quality of PM parts. Properties such as thermal conductivity and specific
heat capacity can be used for quality evaluation of PM components, simulations/
modeling, process parameter optimization and more. Here, Dr Artem A Trofimov,
Orton Ceramic Foundation, evaluates the relatively new Hot Disk Transient Plane
Source (TPS) technique for measuring the thermal properties of loose powders
and compressed tablets, and discusses its potential for quality control via quick
differentiation between powders of different metals and/or particle sizes using
thermal property calibration curves.
