超塑性等温锻造工艺现在已成功地用于生产F-15战斗机用F-100发动机IN100合金压气机盘和涡轮盘。采用这种工艺比用强度较低的合金锻造相同结构的盘件所需要的锭坯投料重量大约能减少80％。由于在这种工艺上积累了大量经验并且改进了盘件检验方法,现在对同样的锻件能够再减少锭坯投料重量的50％,总 Superplastic isothermal forging process has now been successfully used to produce F-100 fighter F-100 engine IN100 alloy compressor disc and turbine disc. Using this process requires about 80% less weight for the billet than for forging disks of the same construction with lower strength alloys. Due to the extensive experience gained in this process and the improvement of the disc inspection method, the same forging can now be re-reduced by 50%
