摘要

采用X射线衍射、扫描电子显微镜、透射电子显微镜研究了Cu Ti B粉末在机械合金化过程中的结构变化。结果表明 :Cu Ti B混合粉末随机械合金化时间的增加

粉末颗粒和α Cu的晶粒尺寸不断细化、应变不断增加 ;机械合金化可以加大Ti和B在α Cu中的固溶度

B的加入促进了Ti在α Cu中的溶解

使Cu Ti B粉末机械合金化的进程加快。

Abstract

The structural transformation of Cu Ti B mixed powders during mechanical alloying has been investigated by XRD

SEM and TEM. The results showed that powder particles and α Cu grain sizes in Cu Ti B mixed powder were fined and strain was increased continuously with the increase of mechanical alloying time. The dissolvability of Ti and B in α Cu could be enhanced through mechanical alloying. B addition could promote the dissolution of Ti in α Cu so as to accelerate the mechanical alloying process of Cu Ti B powder.
