摘要
A series of new alloys including Pd-Ru-M (M=Zr,Mo,Y) were invented in this study.The physical properties,electrical properties parameters and thermodynamics database of the alloys were established.The phase structure and composition were analyzed.The calculation results were verified by experiments.The influence of solidification rate to microstructures,morphology and grain size of Pd-Ru-M alloys were analyzed.According to First Principle,the electronic structures,bonding characters and energetic stability of the alloys were calculated,the calculate result indicated that Pd-Ru-Mo is formed more easily than Pd-Ru-Zr and Pd-Ru-Y,and the formed Pd-Ru-Mo is more stable than Pd-Ru-Zr and Pd-Ru-Y.
