摘　　要：当前全球低碳绿色发展已刻不容缓,氢能作为零碳能源呼声高涨。氢储运环节是产业链中极其重要的一环,而管道输氢最为经济高效,但管线钢处于直接氢气环境中,面临的氢损伤问题再度成为学界热门。文章重点综述了氢分子在钢表面转化为氢原子的吸附渗入过程和氢脆微观机理的最新研究进展;总结了管线钢强度、微观组织、氢陷阱等材料性质和氢气分压、温度、载荷等外部环境因素与氢损伤之间的关系,进一步归纳了预防和抑制管线钢氢脆行为的方法,最后对管线钢氢损伤研究过程中当前面临的难题提出了具体建议。At present,the global low-carbon and green development is urgent,and the voice of hydrogen energy as a zero-carbon energy is rising.Hydrogen storage and transportation is an extremely important part of the hydrogen industrial chain,whilst,among others the pipeline transportation is the most economical and efficient way.However,the pipeline steel is in direct contact with hydrogen,and thus the issue of hydrogen induced damage has become a hot topic again.This review focused on the advancements of how are hydrogen molecules adsorbed and converted into hydrogen atoms on the steel surface and then permeated inwards,as well as the microscopic mechanism of hydrogen embrittlement.The relationships between the hydrogen embrittlement susceptibility with the properties of pipeline steel,such as strength,microstructure,hydrogen traps,and the external environmental factors,such as hydrogen partial pressure,temperature,and load,are summarized.The methods for preventing and inhibiting the hydrogen embrittlement of pipeline steel are further summarized.Finally,specific suggestions are proposed for the current difficulties in the study of hydrogen damage related with pipeline steel.
