after polishing). During ball milling, the ratio of the newly generated surface to the oxidized surfaces of the alloy subjected to interval milling was smaller than that of the alloy subjected to continuous milling. Therefore, the friction coefficient of the surface of the alloy subjected to interval milling was higher than that of the alloy

In another study by Hansung Lee et al., Fe, Co, Ni, Al, and Si powders were subjected to ball milling with a pellet ratio of 10:1 and a ball milling time of 48 h. This enabled the successful preparation of FeCoNiAlSix (x = 0, 0.2, 0.4, 0.6, 0.8) series high entropy alloys using spark plasma sintering. Whereas there have been numerous studies ...

The fcc intermetallic compound Ni 3 Al was subjected to mechanical milling in a high energy ball mill [64]. It transformed from an ordered fcc structure to a disordered fcc solid solution, and then to mixed phases of nanocrystalline and amorphous structure after continued milling.

The effects of ball-milling parameters. During ball milling, kinetic energy from the milling balls can be inelastically transferred to the solids, leading to chemical and physical transformations.

To improve the dispersion stability, MWCNT, were subjected to ball milling with 300 rpm for 1 h to reduce the length of the MWCNT to improve the functional groups to the MWCNT wall during chemical functionalization. MWCNTs were subjected to thermal oxidation in air at different temperatures before acid treatment to remove the amorphous …
