摘　　要：高温强化铂合金是一种先进的高温结构贵金属材料,论述了固溶强化、弥散强化和沉淀强化等铂合金强化方法及特点,力学性能和强化机理,介绍了高温强化铂合金的的研究进展和主要应用情况,最后展望了高温强化铂合金的研究方向。Strengthened Ptbased materials are advanced type of structural and high-temperature precious metal materials. Platinum material strengthening methods e.g. solid solution strengthening, dispersion strengthening, precipitation strengthening and the main features of high temperature alloys are reviewed, and mechanical properties and strengthening mechanism of strengthened Pt-based materials are introduced. The research progress and usages of the major typical strengthened Pt-based super alloys are described. Finally the research directions of Pt-based superalloys are prospected.
