Mechanoactivation of Ni-Al Blends in a Ball Mill: Influence of Ball/Mill Ratio

摘要

Influence of ball/mill ratio on the characteristics of Ni-Al blends mechanically activated in a ball mill was explored. Burning velocity, microstructure of composite particulates, parameters of XRD diffraction patterns, density of green compacts, and their elongation during combustion were measured as a function of the overall mass (m) of the balls placed in the vial. Variation in ball/mill ratio can be suggested as a tool for regulating the basic parameters of mechanically alloyed Ni-Al blends.
