摘　　要：概括论述了铱的特点和纯铱在室温条件下脆性断裂的几种可能机制,说明了纯铱在超高温应用领域存在的问题;系统地综述了世界各国在铱合金多元化方面的研究思路和取得的研究成果,展望了铱基合金在高温结构材料领域的发展前景,最后特别指出了铱合金未来的研究方向。The characteristics of iridium and the possible mechanisms of the brittle fracture of pure iridium at room temperature were discussed and the problems were also described in the application of pure iridium at ultra-high temperature. The research ideas as well as achievements on the diversification of iridium alloys in the world were reviewed. Finally the future development prospects of iridium alloys used at ultra-high temperature were presented and the research directions in the future were also pointed out.
