="ChDivSummary" name="ChDivSummary">The shear banding instability occurs as the homogenous deformation in metallic glasses(MGs) develops to a critical point, at which the discontinuity in deformation...,dilatancy and structural evolution; the shear banding is regarded as the appearance of instability in the constitutive description of inelastic deformation. Tying the bifurcation theory to the new......
Influence of external constraint and rolling geometry on deformation banding of copper single crystals with {123}<634> orientationYanping Zeng, Jianxin Dong, Maicang Zhang, Xishan Xie, Weimin... them into metal frames of different strengths. The metal frames were made of aluminum and mild steel, respectively. The results show that the deformation banding degree of the crystal increases......
Influence of Shear Banding on the Formation of Brass-type Textures in Polycrystalline fcc Metals with Low Stacking Fault EnergyHaile Yan1,Xiang Zhao1,Nan Jia1,Yiran Zheng1,Tong He21. Key Laboratory... and deformation microstructures.It was found that in fcc metals with low SFE at large deformations,the copper-oriented grains rotated around the <110> crystallographic axis through the brass-R orientation......
