本文研究了氢、应力和介质三者对奥氏体不锈钢的协同作用。从实验上证实了氢对材料的腐蚀有加速作用,在和应力的协同作用下,腐蚀速度可进一步增加;在应力腐蚀比较敏感的体系中,舍氢样品比不合氢样品的断裂时间缩短一个数量级,应力腐蚀开裂规一化门槛值下降20％。在理论上对实验结果进行了分析和数学推导,得出了相应的数学表达式。
This paper studies the synergistic effect of hydrogen, stress and media on austenitic stainless steel. It has been experimentally confirmed that hydrogen accelerates the corrosion of materials and the corrosion rate can be further increased under the synergistic effect with stress. In the system where stress corrosion is relatively sensitive, the breaking time of hydrogen-donating samples is one order of magnitude shorter than that of hydrogen- , Stress corrosion cracking normalized threshold value decreased by 20%. In theory, the experimental results were analyzed and mathematically deduced, and the corresponding mathematical expressions were obtained.
