机械合金化——新型固态非平衡加工技术

MECHANICAL ALLOYING——A NEW TECHNOLOGY OF NON-EQUILIBRIUM PROCESSING IN SOLID STATE

机械合金化是一种新型固态非平衡加工技术。本文回顾了机械合金化过程的唯象学描述 ,并阐述了机械合金化形成非晶、纳米晶。

In this paper,mechanical alloying as a new technology of non equilibrium processing in solid state is introduced.In addition ,the phenomenological descriptions of mechanical alloying are rerviewed.The brief mechanisms of preparing such metastable structures as amorphous, nanocrystalline,and supersaturated solid solution materials are also reviewed.Finally,the applications of mechanical alloying are summarized.
