摘　　要：就近年来人们对油气管材应力诱导腐蚀电化学行为的研究进行了评述,分析了应力诱导对油气管材腐蚀热力学、腐蚀动力学和腐蚀产物膜的影响,并对该领域未来的研究方向进行了展望。In the oil and gas industry,the effect of stress on corrosion of steels for pipes can not be ignored due to the environment of complex corrosive media and the applied multiple stress loads on pipes during service.The synergistic effect of stress and corrosive medium can not only cause stress corrosion cracking of oil and gas pipes,but also influence corrosion behavior of steels for oil and gas pipes by changing their electrochemical process.Therefore,the research on the stress induced corrosion electrochemical behavior of steels for oil and gas pipes was commented in this paper.The effect of stress on corrosion thermodynamics,corrosion kinetics and corrosion product film of steels for oil and gas pipes was analyzed.At last,the research trend of the stress influenced corrosion electrochemical behavior of steels for oil and gas pipes was discussed.
