High-Energy Ball Milling - an overview ScienceDirect

High-energy ball milling is a ball milling process in which a powder mixture placed in a ball mill is subjected to high-energy collisions from the balls. High-energy ball milling, also called mechanical alloying, can successfully produce fine, uniform dispersions of oxide particles in nickel-base super alloys that cannot be made by conventional powder metallurgy methods.

Milling Energy - an overview ScienceDirect Topics

Ball milling is a mechanical process and thus all the structural and chemical changes are produced by mechanical energy. 100 Baek et al. 101 recently proposed that edge-selectively functionalized graphene nanoplatelets (EFGnPs) as metal-free electrocatalysts for ORR can be large-scaled prepared by ball-milling method. The EFGnPs were obtained simply by dry ball-milling graphite in the presence of
