High-Energy Ball Milling
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

The ball milling deagglomeration behavior of the different powders obtained under different conditions of high energy milling were similar to that shown in Fig. 2(b). Fig. 2 (c) shows that a higher amount of deflocculant is necessary for dispersion of the high-energy milled powder with MP=15:1, for 4 h and deagglomerated by 10 h of ball milling.

Effect of high energy ball milling on the morphology
High energy ball milling enables the effective superimposition of several strengthening mechanisms, including nanoparticle dispersion, fine grain size and high dislocation density and substructure. On the other hand, if brittle ceramic particles are present as reinforcement, they interfere with the kinetics of the process [33] .
