摘　　要：采用超塑性等温锻造工艺对TC11钛合金航空发动机的压气机盘进行了研制。在模具材料采用镍基铸造高温合金,用玻璃型润滑涂料,模具加热温度控制在950～960℃,坯料加热为950℃保温1.5～2小时的情况下,进行超塑性等温锻造时能获得外观尺寸精确,组织性能都能符合技术要求的盘件。A Disk for compressor used in aviation,which was made of titanium alloy, has been studied by means of isothermally superplasic forging, it is shown that the disk with a defined accuracy size and a desired microstructure can be obtained when the mould was made of cast superalloy with glass lubricant the mould was heated at 950℃ - 960℃ ,and the alloy was treated at 950 for 1. 5 - 2hrs.
