1.前言铂族金属及其合金是国防、仪表、化工及环境保护等工业中的重要材料,其理论基础之一的相图研究与新材料的开拓和合理使用有着密切联系。在文献出版之后,贵金属二元系的相图研究,近十年来有较大发展。作者将这些二元系相图和部分化合物结构归纳整理,提供冶金和材料研究者参考。 1. Introduction PGMs and their alloys are important materials in industries such as defense, instrumentation, chemical engineering and environmental protection. The phase diagram study of one of its theoretical foundations is closely related to the exploration and rational use of new materials. After the publication of the literature, the phase diagram of the precious metal binary system has been greatly developed in the past ten years. The author summarizes these binary system phase diagrams and some compound structures to provide reference for metallurgical and material researchers.
