〔粉体粉末冶金協会平成9年度春季大会協会賞〕受賞記念講演 Formation and Size Controlling of Metallic Alloy Powders by Mechanical Alloying (特集 多元系混合粉の焼結過程および焼結機構) Formation and Size Controlling of Metallic Alloy Powders by Mechanical Alloying
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.
