| 摘 要： | 为鉴定０７ＭｎＣｒＭｏＶＲ钢焊件的疲劳性能，通过试验得到了焊接接头以及焊接热影响区的疲劳裂纹扩展速率，同时给出了它们存活率为９７．７３％时的各自疲劳裂纹扩展速率，并对焊接接头与焊接热影响区疲劳裂纹扩展速率进行比较。最后还把结果与“在役含缺陷压力容器安全评定规程”［１］和ＢＳＩＰＤ６４９３［２］推荐结果进行了对比，认为该钢种疲劳裂纹扩展速率在其容许范围内慢于１６ＭｎＲ钢的疲劳裂纹扩展速率

| Abstract: | In the welded joint zone the micro cracks appear very easily, so the study of the fatigue crack growth rate in the welds is very important. To evaluate the fatigue characteristic of 07MnCrMoVR steel in the welded joint and in the heat affected zone,the crack growth rates are obtained through the tests of CT specimen. The crack growth rates of two zones are compared . Also the results are compared with the formulae in the references and .The results show that the fatigue crack growth in 07MnCrMoVR steel is within the range of references 1 & 2 and is slower than the fatigue crack growth of 16MnR. |
