摘　　要：目的揭示服役寿命长、工况苛刻、锻造成本高、质量控制难度大的航空结构件与发动机盘件用钛合金、高温合金等锻件外观缺陷的产生原因及控制措施。方法按照航空锻件锻造流程(开坯、制坯、模锻和锻后热处理),分别研究裂纹、折叠、错移等锻造缺陷产生的原因。结果航空锻件产生表观质量缺陷的原因一般由工艺设计不合理、锻造操作不当、工装设备保障不到位等导致,需结合锻件材料、形状、变形过程等采取对应措施进行优化解决。结论对航空锻件缺陷产生原因进行了研究,给出了行之有效的解决措施,对于航空锻件质量的提高,尤其是新材料、大尺寸、复杂结构的航空锻件研制具有重要的工程指导意义。The work aims to reveal the causes and control measures of appearance defects in forging links of titanium alloy and superalloy forgings for aviation structural parts and engine parts with long service life,harsh working conditions,high forging cost and difficult quality control.According to the forging process of aviation forgings(blank opening,blank making,die forging and post forging heat treatment),the causes of forging defects such as crack,folding and dislocation are studied,respectively.The appearance quality defects of aviation forgings are usually caused by unreasonable process design,improper forging operation and inadequate equipment support.It is necessary to take corresponding measures to optimize combined with the forging material,shape and deformation process.In this paper,the causes of aviation forging defects are studied,and effective solutions are given,which has important engineering guiding significance for improving the quality of aviation forgings,especially for the development of aviation forgings with new materials,large-size and complex mechanisms.
