摘要

采用熔炼法制备了CuZn（40-x）Mgx合金

借助光学金相显微镜、差热分析仪以及X射线衍射仪

研究了Mg含量对铜锌合金熔点、相转变温度及相变过程微观组织演变的影响。结果表明

当Mg含量大于4%时

CuZn（40-x）Mgx合金析出Cu2Mg相;CuZn（40-x）Mgx合金相转变温度随Mg含量的增加而降低;随着Mg含量的增加

CuZn（40-x）Mgx合金熔点降低。

Abstract

CuZn（40-x）Mgx alloy（x=2%

in atom fraction）was prepared by ingot melting method.Effects of Mg content on melting point

phase transformation temperature and microstructural evolution of the alloy were investigated by OM（optical microscope）

differential thermal analyzer and X-ray diffractometer.The results indicate that with Mg content more than 4%

Cu2Mg phase can be observed in the CuZn（40-x）Mgx alloy.Phase transformation temperature and melting point of the alloy are decreased with increasing in Mg content.
