摘要
本文在不同分压氢气环境中对材料为X42,X52,X60,X70和X80的管线钢材料进行慢应变速率拉伸、断裂韧性和疲劳裂纹扩展测试,研究了含氢气体对管线钢强度、塑性、断裂韧性和疲劳裂纹扩展速率等性能的影响,讨论了氢分压对管线钢材料氢环境相容性的影响,提出了适于管线钢氢环境相容性量化评价的关键力学性能指标和相应的指标测试方法,以便科学评估管线钢材料对氢环境的适应性。
In the present work,slow strain rate tension test,fracture toughness test,and fatigue crack growth test were performed on different pipeline steels,including X42,X52,X60,X70 and X80 in gaseous hydrogen environment with different hydrogen partial pressure.Based on the obtained results,the effects of gaseous hydrogen on the strength,ductility,fracture toughness,and fatigue crack growth rate as well as the major factors that may impact the evaluation of compatibility of pipeline steels with hydrogen were discussed.And the key indexes to assess the compatibility of pipeline steel with gaseous hydrogen,as well as the corresponding test methods were proposed to evaluate the adaptability of pipeline steels in gaseous hydrogen environment scientifically.
