机械合金化─研制生产金属材料的一种新工艺

本文介绍了机械合金化的工艺特点。用机械合金化技术可以获得一些常规方法难以制备的新型合金及难以获得的独特性能，如生产ＯＤＳ合金和弥散强化复合材料，扩大合金元素在基体中的固溶度，获得非晶态合金（金属玻璃），合成金属间化合物材料，获得纳米结构材料。在金属材料研制生产中，机械合金化是一项值得大力研究开发的新技术。

Mechanical Alloying-Advanced Technique for Developing Metallic Materials

The technique characteristic is introduced in this paper. Some new alloys and particular properties which are difficult to obtain by a conventional method may be available when mechanical alloying technique is utilized, such as producing ODS alloys and dispersion strengthened composites, exending solid solubility of alloying element in matrix, obtaining amorphous alloys(metallic glass), synthesizing intermetallic materials and obtaining nano-crystalline materials. Mechanical alloying is a new technique deserving to be developed in research on metallic materials.
