综述了管线钢发生氢致开裂的影响因素及机理的研究现状。分析了材料因素、应力因素和环境因素对氢致开裂的影响,认为材料性质是影响氢致开裂的主要因素。提出了氢致开裂研究中存在的问题,并指明未来氢致开裂的研究方向。
The research progress of influence factors and mechanisms of hydrogen induced cracking(HIC) appearing in pipeline steel was reviewed. The influences of material factors, stress factors and environmental factors on the hydrogen-induced cracking were analyzed. Then, the material properties were taken as main factors in HIC.The problems in the present research of HIC were put forward. Meanwhile, the research direction of HIC in the future was pointed out.
