Ball Milling And Mechanical Grinding

The formation of an amorphous phase by mechanical grinding of a y-co intermetallic compound in 1981 (ermakov et al., 1981) and its formation in the ni-nb system by ball milling of blended elemental powder mixtures (koch et al., 1983) brought about the recognition that this technique is a potential non-equilibrium processing technique.Beginning.
