摘要: 本文对16Mn、08PVXt、440C和4340钢在蒸馏水和3.5%NaCl水溶液中的疲劳裂纹扩展速率(FCGR)进行了实验研究,并与一些钢在同类介质中的腐蚀疲劳(CF)实验结果进行了对比。结果表明:一般钢在前种介质中的疲劳寿命(FL)较后者长;08PVXt、440C及4340钢在蒸馏水中的FCGR较NaCl水溶液中高。而16Mn钢则有相反的结果。作者认为,这种情况是由于Cl~-在裂纹萌生和宏观裂纹扩展过程中起的不同作用所致。
Abstract:The fatigue crack growth rate (FCGR) of 08PVXt, 16Mn, 440C and 4340 steels in distilled water anb NaClaqueous solution has been investigated, and the experimental results have been compared with those of corrosion fatigue in the literature. The fatigue life (FL) of of ordinary steels in distilled water is higher then that in NaCl aqueous solution. The FCGR of 08PVXt, 440C and 4340 steels in distilled water is higher than those in NaCl aqueous solution. However, contrary result is observed for the 16Mn steel. The authors are inclined to think that the function of the Cl~- is different in the crack initiation and in the macroscopic crack propagation.
