从管线钢的氢脆现象、氢脆影响因素以及氢脆机理和研究方法等方面综述了管线钢氢脆的研究现状和进展.介绍其他相关领域研究氢影响材料性能的先进方法及手段,期望管线钢领域借鉴相应的研究方法以明确氢对管线钢性能的影响规律及作用机制,为提出有效的氢脆问题解决方案提供依据,从而保障油气输送管道的安全运行.
The present status on research and development of hydrogen embrittlement of pipeline steel was discussed by illustrating the hydrogen embrittlement phenomenon,influence factors,the rele vant mechanism,and techniques for the study of hydrogen embrittlement.In the meanwhile some new technologies,which were adopted in other areas for characterizing the influence of hydrogen on the performance of materials,were introduced with the hope that such new technologies could be a good refer ence for the researchers and engineers in the study of hydrogen embrittlement of pipeline steel.Thus,precautionary solutions for hydrogen embrittlement of pipelines could be derived subsequently,so that to be beneficial to insure the safe operation of the pipelines.
