我所对航空发动机钛合金压气机盘的锻造工艺进行了重大改进,采用等温精锻新工艺研制成功TC11钛合金压气机盘精锻件。等温精锻新工艺是将模具加热到和TC11锻坯同等的温度下进行锻造,利用TC11在这个温度下具有的超塑性来实现精密模锻。它克服了常规模锻工艺一些固有的缺点,如组织的不均匀,性能的不稳定以及超声波探伤达不到标准要求等,而且由于盘件精度提高,使发动机第 I made a significant improvement on the forging process of the aero-engine titanium alloy compressor disk, and developed the TC11 titanium alloy compressor disk precision forging using isothermal precision forging new technology. Isothermal precision forging new technology is the mold heated to TC11 forging at the same temperature forging, the use of TC11 superplasticity at this temperature to achieve precision forging. It overcomes some inherent shortcomings of conventional die forging process, such as non-uniform structure, performance instability and ultrasonic flaw detection standards, etc., and due to increased disk accuracy, the engine
