微观组织对管线钢氢致裂纹扩展方式及氢捕获效率的影响
Effect of Microstructure on Hydrogen-induced Cracking Propagation and Hydrogen Trapping Efficiency of Pipeline Steel
摘 要
依据NACE TM 0284-2003标准比较了X80和X120管线钢的氢致开裂(HIC)敏感性，采用光学显微镜、扫描电镜观察了裂纹扩展形貌，分析了裂纹扩展与管线钢微观结构之间的关系，依据氢渗透试验结果讨论了管线钢微观组织对氢原子捕捉能力的影响。结果表明，具有针状铁素体组织的X80钢的抗HIC敏感性高于含超低碳贝氏体组织的X120钢; X80钢中HIC裂纹主要沿着多边形铁素体(PF)扩展，X120钢中的HIC裂纹主要沿着原奥氏体晶界扩展; 以板条贝氏体为主的X120管线钢对氢原子的捕获能力大于以针状铁素体为主的X80管线钢。

Abstract
The NACE TM 0284-2003 standard was used to test the hydrogen-induced cracking (HIC) sensitivity of X80 and X120 pipeline steels. The relationship between the crack propagation and the microstructure of the two kinds of pipeline steels was analyzed by optical microscopy and scanning electron microscopy. The hydrogen permeation test was used to quantitatively analyze the influence of microstructure of two types of pipeline steels on hydrogen atom capturing ability. The results show that the HIC resistance of X80 pipeline steel with acicular ferrite is better than that of X120 steel with ultra-low carbon bainite. The HIC crack propagates mainly along the polygonal ferrite in X80 steel while it along the prior austenitic grain boundaries in X120 steel. The X120 steel′s ability to trap hydrogen atoms is greater than X80 steel′s.
