图6 纳米孪晶Cu的晶体结构以及滑移模式[49] (a) a schematic nanotwinned copper microstructure consisting of submicron-sized grains containing parallel nanoscaled twin lamella (M—matrix, T—twin) (b) dislocation slip modes in nanotwinned copper, i.e., slip transfer mode, confined layer slip, twin-ning partial dislocation slip, and ITB migration (b—Burgers vector; b1, b2, b3—Burgers vectors for partial dislocation)
