Abstract
It is well known that the cyclic deformation behavior and dislocation structures of Cu single crystals with different orientations have been systematically investigated and understood. However, there is as yet no general and unequivocal knowledge of the thermal stability of fatigue-induced dislocation structures in Cu single crystals, which is particularly significant for the further improvement of low energy dislocation structure (LEDS) theory. In previous work, the thermal stability of fatigue dislocation structures in [4 18 41] single-slip and [233] coplanar doubleslip Cu single crystals have been reported. For deeply understanding the orientationdependent *国家自然科学基金项目51071041, 51231002, 51271054和51571058,以及高等学校博士学科点专项科研基金博导类项目20110042110017资助 收到初稿日期: 2015-11-09,收到修改稿日期: 2016-01-20 作者简介:郭巍巍,女,蒙古族, 1985年生,博士生 DOI: 10.11900/0412.1961.2015.00572 第761-768页 pp.761-768
