The grinding kinetics of three newly developed master alloys for steel powder metallurgy applications were investigated using a laboratory ball-mill. Non-first order grinding kinetic is observed for the three master alloys as the breakage rate increases with grinding time due to the work hardening of the ductile phase in the microstructure.

ABSTRACT. The top–down approach of mechanical ball milling/alloying is the most commonly adopted route towards materials development. It is however surprising that despite the large impact that it has, process induced contamination (particularly from process control agents (PCAs)), remains less studied and often ignored.
