摘要
本文对40CrNiM_0.钢材在不同热处理工艺下的疲劳门槛值上△K_th进行试验研究,得出了采用870℃油淬,650℃回火工艺,其门槛值最高的结论.
In this paper,the fatigue crack threshol values △Kth in condition of differentheat treatment technology were tested, The maximum threshold value △Kthwas presented,in which the oil quench temperature was 870℃,and temperingtemperature was 650℃.
