Abstract the grinding kinetics of three newly developed master alloys for steel powder metallurgy applications were investigated using a laboratory ballmill. nonfirst 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.
