【摘要】 较全面地介绍600℃时高温钛合金Ti60的组织和力学性能,包括该合金的室温和高温拉伸、持久、蠕变和热稳定性能等,并与国外同类的高温钛合金进行比较。结果表明:该合金与IMI834和Ti-1100合金具有相类似的组织和性能。经双重退火处理后,获得双态组织,并含有强化相α₂和硅化物相。这种组织的合金材料具有优良的综合性能,有望用于制作航空发动机压气机盘和叶片等构件。更多还原

【Abstract】 The microstructure and mechanical properties,such as room and high temperature tensile property,creep property,creep rupture property and heat stability of a high temperature titanium alloy Ti60 were studied,and the alloy with another foreign high temperature titanium was compared.The results show that Ti60 alloy has a comparable microstructure and mechanical property as the IMI834 and Ti-1100 alloy.The precipitation ofα₂ phase and silicides can be observed in Ti60 alloy and the bimodal structure is obtained after duplex heat treatment.Ti60 alloy has excellent mechanical property and is hopeful to be used in the disks and blades of aero engines.更多还原
