【摘要】 采用楔形张开加载(WOL)预裂纹试验方法研究了S30408和S31603在500ppm氯离子溶液中的应力腐蚀裂纹扩展速率。研究结果表明S30408和S31603临界应力强度因子KISCC<110MPa.m0.5,平均应力腐蚀裂纹扩展速率S30408板材约为S31603的2倍,且焊接状态可影响焊接区域应力腐蚀裂纹扩展速率。更多还原

【Abstract】 Stress corrosion research on S31603 and S30408 steel was carried out in 500 ppm CLsolution with the method of pro-cracker wedge-open loading(WOL)test.The results show that the threshold stress intensity factors(KISCC)of the two steels were less than110 MPa.m0.5.the crack growth rate of the S30408 is two times faster than the S31603,The welding condition can affect the stress corrosion crack growth rate in the welding area.更多还原
