氢对管线钢力学性能影响的研究进展
Research Progress on Effects of Hydrogen on Mechanical Properties of Pipeline Steel
摘要
Abstract
In the context of global warming and energy transition,hydrogen energy,as a recognized clean energy,has been included in national energy development plans by countries around the world.Using pipe to transport hydrogen is considered to be the best way to transport hydrogen on a large scale,however,hydrogen may adversely affect the mechanical properties of pipeline steel,thereby increasing the safety risk of the pipeline.Therefore,combined with the theory of hydrogen damage mechanism,this study reviewed the research progress of mechanical properties of pipeline steel in hydrogen doped environment and pure hydrogen environment,such as tensile strength,elongation,fracture toughness,fatigue life and other changes.On this basis,the research direction of hydrogen pipeline steel is summarized and prospected,in order to provide reference for the research direction and technical breakthrough of hydrogen pipeline steel.关键词
