| 摘 要： | The four evolution stages of persistent slip bands (PSBs), namely, the veins, pass, embryos and well-developed dislocation structures of PSBs can be obtained using electron channeling contrast (ECC) technique in a scanning electron microscopy (SEM). For the four stages, the typical dislocation structures are simulated and the stress field is calculated by the discrete dislocation static method.
