摘要 对Inconel 690(TT)合金腐蚀疲劳裂纹尖端塑性区微观结构进行观察,并研究裂纹尖端塑性区及载荷比对模拟压水堆环境下的裂纹扩展行为的影响。裂纹尖端小范围屈服时,模拟压水堆环境对裂纹扩展速率有3倍左右的加速作用。。 Corrosion fatigue crack-tip plastic zone of Inconel 690（TT） was investigated, and the effects of crack-tip plastic zone and load ratio on the corrosion fatigue cracking in the simulated pressurized water reactor environment were studied. The accelerating effects of the simulated pressurized water reactor environment on fatigue crack growth rates under small scale yielding was as large as 3.
