“…Other than the ductile to brittle transition zone, the grain boundary deformation length was significantly higher (~3 times) for the sample Q&P-treated at 310°C, in comparison to the sample Q&P-treated at 190°C (Figures 5(d) and (e)). It is reported [34,35] that a higher prior austenite grain boundary deformation during crack propagation leads to a significant increase in the toughness of the material. Hence, an increase in both the ductile to brittle transition zone as well as the prior austenite grain boundary deformation length led to higher impact toughness for sample Q&P-treated at 310°C.…”

“…The specific role of GBs in affecting cleavage crack growth resistance has not yet been completely clarified. However, recent studies by Qiao [44], Qiao & Argon [45], Qiao & Kong [46], Chen et al [47] and Lu et al [48] should be mentioned.…”

“…Grain boundaries act as natural barriers in cleavage fracture due to differences between the orientations of the cleavage plane in Grain A formed after Stage II and {1 0 0} planes in the neighboring grains [29][30][31][32]. The influence of twist and tilt between the cleavage plane in Grain A and {1 0 0} planes in the neighboring grain should be considered.…”
