The Phase Structures and Properties of Pt-Ir-M (M=Zr, Mo, Y) System

Abstract:

A series of new alloys including Pt-Ir-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 Pt-Ir-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 Pt-Ir-Mo is formed more easily than Pt-Ir-Zr and Pt-Ir-Y, and the formed Pt-Ir-Mo is more stable than Pt-Ir-Zr and Pt-Ir-Y.
