Effects of Ball Milling and Sintering on Alumina and Alumina-Boron

When ball milling, the starting powder gets trapped between the highly kinetic milling balls and the inside surface of the vial. This causes repeated deformation, rewelding, and fragmentation of the starting powder. This causes the formation of fine, dispersed particles in the grain-refined matrix [12].
