摘要：
The influence of post-weld heat treatment on hydrogen-assisted cracking of process pipe steel is investigated in terms of change in hydrogen trapping site. This study reports that, contrary to other microstructures, in acicular ferrite, cementite bodies acting as reversible trapping sites for hydrogen atoms are newly precipitated along the grain boundary by the post-weld heat treatment conducted at 620 degrees C. This leads to an increase in diffusible hydrogen content in the steel that makes it more susceptible to hydrogen-induced cracking. (C) 2012 Acta Materialia Inc. Published by Elsevier Ltd.
