分析了不同热处理工艺对14Cr1MoR铜断裂韧度K_(IC)~J和亚临界扩展速率da/dN的影响。结果表明：经730℃回火后14Cr1MoR钢的断裂韧度K_(IC)~J有较明显的提高,裂纹扩展速率da/dN则无明显变化。
The effects of different heat treatment processes on the fracture toughness K_ (IC) ~ J and the subcritical expansion rate da / dN of 14Cr1MoR were analyzed. The results show that the fracture toughness K_ (IC) ~ J of 14Cr1MoR steel after tempering at 730 ℃ is obviously improved, and the crack growth rate da / dN has no obvious change.
