摘要: 采用光学显微镜、SEM、EDS、硬度测试、电阻率测试和耐硫化测试等方法,研究了Y的不同添加量对银基合金靶材坯料显微组织和性能的影响.结果表明:Y添加量较少时,Y主要以固溶体的形式存在,可以起到细化晶粒的作用,而Y添加量过多时,会有第二相析出.当Y添加量为0.1%时材料综合性能最好,此时银基合金靶材坯料的硬度值较高,电阻率较低,耐硫化性能最佳.

Abstract: The influence of different addition amounts of element Y on the microstructure and properties of Ag-based alloy targets was studied by using optical microscope (OM), scanning electron microscope (SEM), energy diffraction spectrum (EDS), hardness tests, electrical conductivity tests and sulfidation resistance tests. The results indicated that when Y content added to the Ag-based alloy target is small, Y mainly exists in form of solid solution and plays an important role in grain refinement. However, adding excess Y leads to the precipitation of the second phase. The Ag-based alloy targets with 0.1wt% Y addition demonstrates the superior properties: higher hardness, lower electrical conductivity and the most optimal sulfidation resistance.

Key words: Ag-based alloy target, yttrium, microstructure, microhardness, electrical conductivity, sulfidation resistance
