Design and Properties of Bi-Pb-Sn-Cd Fusible Alloys

  • 摘要: 根据铋基合金的特点与合金相图,设计了不同成分的Bi-Pb-Sn-Cd易熔合金;并利用差热分析仪、X射线衍射仪及力学检测设备等研究了成分对合金熔点、组织和抗拉强度的影响。结果表明,设计的易熔合金由Bi、Pb7Bi3、Sn和Cd等物相组成;合金的熔点均在72℃左右。随Cd、Bi元素含量的增加,液相线温度逐渐降低;Cd元素对合金熔程、抗拉强度的影响最大,Sn元素次之,Pb元素的影响最小。正交试验表明,Bi-30Pb-15Sn-9Cd合金的综合性能最佳。
    Abstract: Series of Bi-Pb-Sn-Cd fusible alloys were designed with reference to the characteristics of Bi-based alloy and their phase diagram. The melting point, microstructure and the tensile strength of fusible alloys were determined by DSC, XRD and tension tests. The results show that the fusible alloy is composed by Bi, Pb7Bi3, Sn and Cd phases. The melting point of the all designed fusible alloy is around 72℃. The lquidus temperature falls down with the increase of content of Cd and Bi elements increase. The influence of alloy elements on the melting range and tensile strength are reduced in the order of Cd, Sn and Pb. Among the nine fusible alloys, Bi-30Pb-15Sn-9Cd alloy has the optimum performance according to orthogonal test.
