Mechanical alloying (MA) method using ball-milling and/or rod-milling techniques has been employed for synthesizing several metallic amorphous alloy powders and nanocrystalline powders of metal nitrides, metal hydrides, and metal carbides. This review paper shows: (1) the effect of the milling media (balls or rods) on the solid state amorphization reaction, (2) the effect of annealing on the mechanically alloyed powders and (3) the consolidation of the mechanically reacted powders into full dense nanocrystalline compacts. Some mechanical and physical propertied of the as-consolidated powders are presented.
