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.
