すべり変形にともなう原子空孔濃度の発展に関する検討

抄録

Generation and accumulation of atomic vacancy due to pair annihilation of edge dislocations during plastic slip deformation are evaluated by crystal plasticity finite element analysis. Dislocation density-based models are utilized in the deformation analysis and a theoretical model for vacancy generation is introduced. Purely uniform single or double-slip deformation is analyzed and results show that the evolution of vacancy density depends lagely on the microstructure length scale.
