宝鸡有色金属加工厂和西北工业大学联合课题组经过几年的共同努力,在解决了等温锻造工艺和设备后,在宝鸡成功地锻制了直径520mm TC11钛合金压气机盘。剖盘测试表明,盘件的组织为4级的等轴α+β组织、其室温、高温拉伸性能,持久蠕变性能,热稳定性和缺口 After years of joint efforts, the joint research group of Baoji Nonferrous Metal Processing Plant and Northwestern Polytechnical University succeeded in forging the 520mm diameter TC11 titanium alloy compressor disk in Baoji after solving the isothermal forging process and equipment. The test results show that the disk is organized into 4-level equiaxed α + β microstructure with room temperature, high temperature tensile properties, long-term creep property, thermal stability and notch
