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。 CuZn(40-x)Mgx alloy(x=2%,4%,6%,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.
