摘要

研究了机械合金化法制备Fe Si纳米晶合金

用X射线衍射仪、扫描电子显微镜和X射线能量色散谱仪对经不同机械合金化工艺条件处理的Fe3 3 Si67混合粉末进行了分析

结果表明 :Fe3 3 Si67混合粉末球磨 2 0h后可实现机械合金化。随着球磨持续进行

合金化的粉末和晶粒不断细化

最后可得到Fe Si纳米晶合金

Abstract

Fe-Si nanocrystalline alloy by mechanically alloying m ethod was prepared. Fe 33Si 67 mixture powder treated by various mecha nically alloying processes was analyzed by X-ray diffraction

scanning electron microscope and energy dispersive X-ray analysis system. The results showed tha t Fe 33Si 67 mixture powder could realize mechanically alloying by ball grinding for 20 h. At last

Fe-Si nanocrystalline alloy could be obtained with continuous ball grinding for alloyed powder grain.
