| Abstract: | Pt-5Ru alloys was prepared by vacuum arc melting and a small amount of yttrium was added for dispersion strengthening.The microstructure, mechanical properties and reflectance of Pt-Ru-Y alloys were studied by X-ray diffractometer (XRD), metallographic microscope, microhardness tester and spectrophotometer. The results show that the addition of rare earth element yttrium can significantly refine the grain of Pt-Ru alloy, purify the air absorption effect, reduce the internal defects of the alloy, improve the microhardness of the alloy, and improve the mechanical properties of the alloys. |
