Abstract: Abstract The variant selection and pairing directly affect the grain boundary distribution in the coarse-grained heat-affected zone (CGHAZ) of pipeline steel and consequently impact toughness. In this study, we attempted to establish a direct correlation… read more here.

Abstract: Toughness of the coarse-grained-heat-affected-zone (CGHAZ) strongly depends on the prior austenite grain size. The prior austenite grain size is affected not only by chemical composition, thermal cycle, and dissolution of second-phase particles, but also by… read more here.
