540℃高温钛合金研制及其在压气机叶片方面的应用是由上海钢研所和国营黎阳机械公司合作进行的。这是继79-82年合作研制500℃耐热钛合金(7715B钛合金)后又一次成功的合作。540℃高温钛合金(7715C钛合金)自82年6月起到85年底由上海钢研所完成合金研制和提供热轧棒材后,黎阳公司(一七○厂)于86-87年顺利完成合金棒材复验,WP-13型发动机第八级压气机叶片模锻研制;生产三台份7715C第八级压气机叶片,并进行全叶片自振疲劳测
The development of 540 ℃ high temperature titanium alloy and its application in compressor blades was carried out by Shanghai Steel Research Institute and State-owned Liyang Machinery Company. This is another successful cooperation after 79-82 years of cooperation in the development of 500 ℃ heat-resistant titanium alloy (7715B titanium alloy). 540 ℃ high temperature titanium alloy (7715C titanium alloy) from June 82 to the end of 85 by the Shanghai Steel Research Institute to complete the development of alloys and provide hot-rolled bar, the Li Yang Company (170 plants) completed in 86-87 years Alloy bar retest, WP-13 engine eighth stage compressor forging die development; production of three copies of 7715C eighth stage compressor blades, and full-leaf self-vibration fatigue test
