According to the production situation of 2A14 heat treatment in the company for many years,three quality problems were analyzed.Due to the change of the state of the supplied free forgings,the hardness of part was low after solid solution and aging.Excessive residual stress and deformation after heat treatment caused by improper selection of cutting tools in machining.The tensile data was not true due to the wrong sampling direction.This paper analyzed the above problems,and put forward improvement measures to examine the whole process of parts processing,to control the risk points that might affect the quality of heat treatment,and to ensure the stability of heat treatment quality.
