退火是一种金属热处理工艺，指的是将金属缓慢加热到一定温度，保持足够时间，然后以适宜速度冷却。目的是降低硬度，改善切削加工性；降低残余应力，稳定尺寸，减少变形与裂纹倾.11
Annealing is a metal heat treatment process, which refers to slowly heating the metal to a certain temperature, holding it for a sufficient time, and then cooling at an appropriate rate. The purpose is to reduce the hardness and improve the machinability; reduce the residual stress, stabilize the size, reduce the deformation and crack tilt. (2020-04-09, Delphi, 6188KB, 下载4次)
