六二一所和上钢五厂、三○○七厂、四二○厂等单位自一九八○年五月以来,为满足某机选用TC11钛合金急需,对合金的成份、冶炼工艺、热加工工艺、热处理工艺、组织性能、超声检验等进行了全面试验研究。合金的全面测试结果表明,TC11已达到国外同类合金水平,且在蠕变、热稳定性等方面有所超过。钛盘模锻件的性能测试结果表明,所有技术考核指标均符合规定要求,其中塑性指标、蠕变抗力、热稳定性均较BT9(相应的苏联合金
June 21 and the SSE No. 5 Plant, No. 307 Plant and No. 4 2020 Plant, etc. Since May 1980, in order to meet the urgent need of the TC11 titanium alloy for a certain machine, the composition, smelting process, Thermal processing technology, heat treatment technology, organizational performance, ultrasonic testing conducted a comprehensive experimental study. Comprehensive test results show that the alloy, TC11 has reached the level of similar foreign alloys, and in terms of creep, thermal stability and more. Titanium plate forgings performance test results show that all technical assessment indicators are in line with the requirements, including plasticity, creep resistance, thermal stability than BT9 (the corresponding Soviet Union alloy
