摘要
分析了不同热处理状态对2.25Cr1Mo钢断裂韧度(KIJC)和裂纹扩展速率(da/dN)的影响。结果表明,经730℃回火后2.25Cr1Mo钢的断裂韧度有较大的提高,裂纹扩展速率则无明显变化。
The effect of different heat treatment technologies on crack toughness（KIC^J） and crack propagation rate （da/dN） of 2. 25CrlMo steel are introduced. On the base of analysis, the conclusion is made that the KIC^J value is raised and da/dN has no clearly change after 730 ℃ tempering temperature.
