摘要
机械合金化是一种通过高能研磨实现的固相粉体加工技术。现已证明可以通过对纯组元混合粉或预合金粉进行机械合金化处理,合成包括非晶合金在内的多种平衡与非平衡合金相。主要评述了机械合金化法在非晶态合金材料研究领域的优势和特点,重点介绍了当前有关机械合金化致非晶化机理的研究成果以及未来这一领域的发展方向。
Mechanical alloying (MA) is a solid-state powder processing technique involving repeated welding and fracturing of particles in a high-energy ball mill. It has been shown to be capable of synthesizing a variety of equilibrium and non-equilibrium alloy phases including the amorphous alloy from blended elemental or prealloyed powders. Mechanical alloying is one of the most potential method in the preparation and science research of amorphous alloy. The characteristics and superiority of mechanical alloying on amorphous alloy research are discussed in this article. Additionally, it introduces the present research status of the mechanism of amorphization and the development direction.
