铝合金锻件残余应力和变形关系分析探讨

铝合金锻件在锻造、切削、热处理等加工过程会产生残余应力，当金属内部残余应力平衡时，金属组织性能较高，当金属内部残余应力失衡时，金属内应力发生释放产生变形现象，金属组织性能将有所下降。本文以变形铝合金锻件为研究对象，对残余应力和变形之间的关系分析，并提出预防措施和消除变形的方法。

Analysis and Discussion on the Relationship between Residual Stress and Deformation of Aluminum Alloy Forgings

Aluminium alloy forgings will produce residual stress in the process of forging, cutting, heat treatment and other processes. When the internal residual stress of metal is in balance, the performance of metal structure is higher. When the internal residual stress of metal is unbalanced, the internal stress will be released to produce deformation phenomenon, and the performance of metal structure will be reduced. Taking the wrought aluminiumalloy forgings as the research object, this paper analyses the relationship between residual stress and deformation, and put forward preventive measures and methods to eliminate deformation.
