Amorphization rate highly depends on the kinetic energy of the ball mill charge so particles reacted and interdiffused. Amorphization rate increases with BPR. In the early 48 h of ball milling, an amorphous phase fraction is observed, and then after when it further increases crystalline phase is observed due to the heat generation.
