New insights into the mechanism of cooling rate on the impact toughness of coarse grained heat affected zone from the aspect of variant selection
TL;DR: In this paper, the authors tried to establish a direct correlation between crystallographic variants and impact toughness, and provided some novel insights into the mechanism of cooling rate on the impact toughness of coarse grained heat affected zone (CGHAZ) of offshore engineering steel by means of electron back-scattering diffraction (EBSD) analysis.

Atomic-scale study on segregation behavior at austenite grain boundaries in boron- and molybdenum-added steels
TL;DR: In this article, the authors investigated the effect of boron (B) and molybdenum (Mo) addition on the hardness of low carbon steels and found that the amount of B segregation at the prior austenite grain boundary was mostly independent of Mo content at a high cooling rate of 30°C/s.
