机械合金化是70 年代末发展起来的一种合成材料的新工艺，并由此制备出了一系列的新材料，同时还提出了一系列的理论问题，在材料和机械化学界引起了广泛关注。本文主要介绍了机械合金化的发展简史、特点、影响因素以及研究现状，并提出了一些新的看法。 Mechanical alloying is a new technology of synthetic materials developed in the late 1970s, and a series of new materials were prepared. At the same time, a series of theoretical problems were raised, attracting a great deal of attention in the field of materials and mechanochemistry. This paper mainly introduces the history, characteristics, influential factors and research status of mechanical alloying, and puts forward some new ideas.
