Abstract

The current review paper focused on the effect of crystallographic texture on hydrogen-induced cracking in pipeline steels through a literature review. Analyzing the effect of crystallographic texture on hydrogeninduced cracking in pipeline steel requires distinguishing between two types of crack propagation: intergranular and transgranular. In situations with limited grain boundary mobility at ambient temperature, transgranular crack propagation tends to be the prevailing mode. Grains oriented along <001> //ND in pipeline steels, characterized by less efficient atomic packing, increase the likelihood of transgranular crack propagation. On the contrary, grains oriented along <011> //ND and <111> //ND feature multiple slip systems, making crack propagation more challenging. Both intergranular and transgranular hydrogeninduced cracks can occur through various grain orientations, including <001> //ND, <011> //ND, and <111> //ND. This indicates that although crystallographic texture and grain orientation are significant factors in hydrogen-induced cracking propagation, they are not the exclusive determinants. Therefore, a comprehensive understanding and effective management of hydrogen-induced cracking require consideration of a range of microstructural features. The potential for intergranular crack propagation increases in situations where grain boundaries are high angle or possess high mobility. In such cases, a mismatch in the Taylor factor between adjacent grains can play a role in facilitating intergranular crack propagation. Finally, hydrogen atoms exhibit faster diffusion rates within grains oriented along <001> //ND and <101> //ND compared to those oriented along <111> //ND. However, there is no notable discrepancy in the diffusion behaviors between grains oriented along <001> //ND and <101> //ND.
