Hot pressing of metal powders | SpringerLink

A study was conducted of the hot-pressing kinetics of 20% Cr-80% Ni alloy powder, and the main parameters of the process — the energy of activation and the dependence of process rate on applied load — were determined. It has been shown that the mechanism of densification involves the climb and transverse slip of dislocations.
