چکیده انگلیسی
The effect of the angle θ between loading axis and twin boundary (TB) on the deformation behaviors of nanotwinned Cu was studied by finite-element method (FEM) under tensile deformation. Three different microstructures (θ¯=30°,ϯ=3.7;θ¯=10°,ϯ=3.7andθ¯=30°,ϯ=8.8) were presented. Evolution of equivalent plastic strain showed that the deformation of the three microstructures were distinct on account of θ: the grains with larger θ deformed first; compared with the microstructure with θ¯=10°,ϯ=3.7, the microstructure with θ¯=30°,ϯ=3.7 can effectively delay the onset of shear band. The results demonstrated that an unusual combination of high strength and ductility can be obtained by making a proper arrangement of θ. However, the effect of θ on the stress-strain relations was weakening as twin density lamellae thickness decreases.
