摘　　要：研究了Ti60高温钛合金环材的组织和性能。结果表明,该合金环材经双重退火后的显微组织为双态组织,并含有强化相α2相及硅化物相;这种组织的环材具有良好的室温拉伸、高温拉伸、热稳定、蠕变和断裂韧性等性能匹配,它的各项主要性能与IM I834钛合金相当,可用于制作航空发动机压气机压气盘、叶片等构件。The microstructures and properties of Ti60 alloy ring material have been studied. The results show that the alloy has bimodal structure and strengthening α2 phase as well as silicide phase. The material has good tensile properties both at room temperature and at 600 ℃, thermal stability, creep property and fracture toughness. The main properties of Ti60 are comparable with those of the titanium alloy IMI834 and can be used in the aerospace field for manufacturing engine, compressor, blade, and so on.
