摘　　要：通过分析与对比三型热强钛合金压气机盘锻件的显微组织要求、力学性能项目,以及取样部位要求方面存在的差异发现:标准挑选典型的轮缘、幅板、轮毂为显微组织检验部位,匹配盘锻件变形特征;TC11与TC8-1合金锻件显微组织等级要求不符合变形未充分组织特点;轮毂部位需检测高温拉伸、高温持久性能,幅板部位需检测疲劳性能与断裂韧度。从实际检验测试结果来看,三种轮盘均满足标准要求,因此可考虑对标准完善,严格检验要求。Application of three kinds thermal-strength Titanium alloys on aero-engineer compressor disk were analyzed.Comparing requirement of standards for microstructure,mechanical properties and site of specimens.The results showed that:rim,hub,board are typical sites for microstructure testing,requirement for forging microstructure was not matched with insufficient deformation microstructure.high temperature stretch and rupture measurements should be implement on rim part,while fatigue and fracture roughness test should on board part.Actual inspection result of disk showed that:disk forge meet demand of forging standards,it is feasible that require high standards and improve it.
