Self-Propagating Reactions Induced by Mechanical Alloying ...

Mechanical alloying is a "brute force" method of affecting alloying and chemical reactions. The mixture of reactant powders and several balls are placed in the milling jar of a high-energy ball mill, for example, a shaker mill or a planetary mill (Figure 1). The collisions and friction between the balls, and between the balls and the wall of the container, result in deformation, fragmentation, mixing, and cold-welding.
