A number of investigations reveal that fatigue crack mainly initiates along persistent slip bands (PSBs) in copper single crystals at low or medium strain range, however, nucleates along coarse deformation bands (DBs) at high strain range. For copper bi-crystals, various large-angle grain boundaries (GBs) are always the preferential sites for the nucleation and propagation of fatigue cracks while the low-angle GBs do not lead to fatigue cracking during fatigue. Fatigue cracks mainly nucleated along large--angle GBs, sometimes along PSBs in polycrystalline copper, however, the initiation of fatigue crack at twin boundaries (TBs) was not observed due to the compatible slip deformation across the TBs. Key words： copper crystal    fatigue crack    persistent slip band (PSB) 收稿日期: 2005-06-30      ZTFLH:  TG113.25   服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 张哲峰 段启强 王中光 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y2005/V41/I11/1143 [1] Forsyth P J E.
