Abstract
Microstructural evolution in gas-atomized Al-14 wt%Ni-14wt% Mm alloy powders was studied during mechanical milling. It was noted that the as-solidified particle size of 200 μm increases up to 72 h of milling and, subsequently, there was continuous refinement to 20 μm on milling to 200 h. Two microstructurally different zones-Zone A, which is featureless, and Zone B, which has the structure of the as-solidified powder-were noted. The thickness of the Zone A increased with increasing milling time at the expense of Zone B. Zone A was found to be much harder than Zone B and, consequently, crack formation, eventually leading to microstructural refinement, was observed to start in the relatively weaker Zone B.
