WebNov 16, 2024 · The study provides novel findings: Dislocations are emitted from the crack fronts along the {110} cleavage plane, and this phenomenon explains why the {100} plane can be the cleavage plane.... WebJan 15, 2024 · Ming et al. realized a synchro- nized increase in strength and ductility of single FCC-phase CrFeCoNiMo alloy by developing hierarchical microstructure that comprises annealing nano-twins in recrystallized fine grains and stable dislocation walls in non- fully recrystallized fine grains [15].

WebSep 8, 2024 · During the tensile process, the crack tip is always in a state of high stress and continues to emit dislocations, which deviate from the crack and move toward the crystal interior. The dislocations are continually emitted and slippage, and the region they pass through forms the DFZ region. WebMar 6, 2024 · This is owing to the differences in the capacity to absorb and emit dislocation between GBs with different structures. In previous studies, the majority of researchers kept their focus on the atomic structure, formation mechanism, or reaction with incoming dislocations of a certain GB. ...
