摘　　要：本文针对金属基金刚石工具在使用过程中存在的Fe-Cu固溶度有限带来的金刚石工具使用寿命不长的问题,通过对Fe-Cu复合粉体进行高能球磨,来增加Fe-Cu粉体的固溶程度和合金化,来改善和提高金刚石工具的使用寿命。因此,本文主要研究了在高能球磨过程中Fe-Cu复合粉体的粒度变化情况,通过对Fe-Cu粉体采用不同的两种球磨方式,研究在球磨过程中粒度的变化情况,从而讨论机械合金化对Fe-Cu固溶及合金化程度的影响。In view of the metal fund corundum tools exist in the using process of Fe-Cu solid solubility limited service life of diamond tool is not a long problem, by means of Fe and Cu composite powder with high energy ball mill, to increase the degree of Fe-Cu powder of solid solution and alloying, and to improve and enhance the service life of diamond tools. Therefore, this article mainly studied in the process of high-energy ball mill Fe-Cu composite powder particle size changes, by means of Fe-Cu powder different two ball grinding method, studies the change of particle size in the process of ball mill, so as to discuss the mechanical alloying of Fe-Cu solid solution and the influence of alloying degree.
