摘　　要：实验研究了Sb_(20-x)Sn_(80)Zn_(x)(x=2,4,8,10)合金的相转变及微观组织结构。采用X射线衍射(XRD)、扫描电镜(SEM)对Sb_(20-x)Sn_(80)Zn_(x)(x=2,4,8,10)合金的相组成、相结构及微观组织进行了表征。结果表明,Sb_(18)Sn_(80)Zn_(2)合金中含有BCT(Sn)相和Sb_(3)Sn_(4)相,Sb_(16)Sn_(80)Zn_(4)合金中含有BCT(Sn)相、Sb_(3)Sn_(4)相和Sb_(2)Sn Zn相,Sb_(12)Sn_(80)Zn_8合金中含有BCT(Sn)相和Sb_(2)Sn Zn相,Sb_(10)Sn_(80)Zn_(10)合金中含有BCT(Sn)相、Sb_(3)Zn_(4)相和Sb_(2)Sn Zn相。随着Zn含量的增加,Sb_(3)Sn_(4)相的体积分数不断减少,而Sb_(3)Zn_(4)相的体积分数不断增加。通过差热分析(DTA)对Sb_(20-x)Sn_(80)Zn_(x)(x=2,4,8,10)合金的相转变进行了分析,确定了相转变温度和液相温度。The phase transformation and microstructure of Sb_(20-x)Sn_(80)Zn_(x)(x=2,4,8,10)alloys were investigated.The phase composition,phase structure and microstructure of Sb_(20-x)Sn_(80)Zn_(x)(x=2,4,8,10)alloys were characterized by X-ray Diffraction(XRD)and Scanning Electron Microscopy(SEM).The results show that the Sb18Sn_(80)Zn_(2)alloy contains BCT(Sn)phase and Sb_(3)Sn_(4)phase,the Sb_(16)Sn_(80)Zn_(4)alloy contains BCT(Sn)phase,Sb_(3)Sn_(4)phase and Sb_(2)SnZn phase,the Sb_(12)Sn_(80)Zn_(8) alloy contains BCT(Sn)phase and Sb_(2)SnZn phase,and the Sb10Sn_(80)Zn_(10) alloy contains BCT(Sn)phase,Sb_(3)Zn_(4)phase and Sb_(2)SnZn phase.With increasing Zn content,the volume fraction of the Sb_(3)Sn_(4)phase decreases while the volume fraction of the Sb_(3)Zn_(4)phase increases.The phase transition of Sb_(20-x)Sn_(80)Zn_(x)(x=2,4,8,10)alloys were analyzed by Differential Thermal Analysis(DTA)to determine the phase transition temperature and the liquidus temperature.
