corrosion fatigue

Because hot work dies suffer from various physical and chemical actions, such as wear, thermal fatigue, erosion, stress corrosion and surface thermal wielding in service, their service life are not long.

热作模具在使用过程中承受着磨损、热疲劳、冲蚀、应力腐蚀、表面热焊合等物理、化学作用，因而其使用寿命较低。

This is confirmed by SEM that it is caused by corrosion fatigue.
