摘要
试验得出了 0 Cr1 8Ni9钢在质量分数为 0 .1 % Na Cl溶液中 4个不同加载频率下的腐蚀疲劳裂纹扩展速率。结合试验结果 ,并采用数学分析方法 ,给出了环境加速因子 C( f)的表达式 ,进而提出了一种腐蚀疲劳裂纹扩展速率的 dad N～ (ΔK ,f )数学计算模型。
The corrosion fatigue crack growth rates of 0Cr18Ni9 steel in 0.1% NaCl solution were experimentally obtained under four different loading frequencies. An expression of environmental accelerating factor, C(f) was put forward with testing results, and then a mathematic model of corrosion fatigue crack growth rate,d a d N～(ΔK,f) was derived.
