| 摘 要： | 在Pt-Ir系中分别加入Zr、Mo、Y三种元素,研究稀有金属元素的加入对Pt-Ir系组织结构及力学和电学性能的影响.合金相在真空高频炉中熔炼.用X射线衍射仪和金相显微镜对合金相的显微组织和结构进行分析,用电桥、涡流导电仪测量合金相的电阻率,用拉力试验机测量合金相的力学性能.结果表明:稀有金属元素的加入可以有效地细化合金相的显微组织,并且提高合金相的熔点、密度、力学性能和电阻率,但是合金相的加工性能有所降低.

| Abstract: | The effect of Zr, Mo or Y doping on mechanical and electrical properties of Pt-Ir binary alloys was investigated. The alloys were prepared in a vacuum high frequency melting furnace. X-ray diffraction and metallographic microscopy were employed to detect the microstructures. Electric bridge and eddy current conductive instrument were employed to test the electrical resistivity and the mechanical properties of alloys were tested by AG-X100KN type tensile testing machine. The results show that adding rare metal elements into Pt-Ir system could refine structure effectively, increase the melting point, density, mechanical properties and electrical resistivity of the alloys, but decrease the processing property. |
