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.
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.
