Microstructurally, the mechanical alloying process can be divided into four stages: (a) initial stage, (b) intermediate stage, (c) final stage, and (d) completion stage. (a) At the initial stage of ball milling, the powder particles are flattened by the compressive forces due to the collision of the balls.
