| 英文摘要 | The evolution from the so-call matrix vein to persistent slip bands (PSBs) in a fatigued copper single crystal of single-slip-oriented has been investigated by using electron channeling contrast (ECC) technique in a scanning electron microscope (SEM). The distribution of the internal stress field of typical dislocation structures in consecutive stages of PSBs formation was calculated by the method of discrete dislocation distribution. The results show that the distribution of internal stress is non-uniform in the evolution process from matrix vein to PSBs dislocation structures. In the dislocation dense regions (matrix vein and PSBs walls) the distribution of the internal stress is relatively more concentrated than that in the dislocation poor regions (channel). In a PSB the internal stress distribution is apparently weaker than that in matrix after the PSBs well formed. At the interface between PSBs and matrix, the stresses have a sharp transition. Finally a possible mechanism for PSBs formation was proposed. |
