摘　　要：本文简要介绍了国内外在机械合金化研究和发展新材料方面的概况．扼要阐述了本实验室近年来在这方面取得的进展，例如机械合金化过程中的热力学、动力学及非晶转变机制。在无化学驱动力系统中的非晶转变，纯金属与非晶合金的机械合金化，球磨对晶态合金结构的影响，Ｆｅ与ＣｕＯ间的置换反应，Ｆｅ－ＳｉＣ复合纳米相的制备，制取纳米合金的新方法等．In this paper the study of mechanical alloying and its development in making new materi-als at home and abroad are introduced briefly. The progress of the study of mechanical alloy-ing in our lab in recent years is also related. Descriptions will include (1) thermodynamics, kinetics and transition mechanism for amorphization during mechanical alloying, (2) the amorphization transition in a system without chemical driving force, (3) mechanical alloying of pure metals and amorphous alloys, (4) the influence of ball milling on the structure of crystalline alloy, (5) the displacement reaction between Fe and CuO, (6) the preparation of nanocrystalline Fe-SiC composites, (7) a new method for preparing nanocrystalline alloys, etc.
