摘要: 系统地观察了各种不同轴向Cu晶体的循环应力-应变响应及其饱和位错结构.实验结果表明,晶体的宏观循环形变行为和微观位错组态的演变都与晶体的轴向紧密相关.在一些轴向位于标准取向三角形内的单滑移晶体中观察到明显的多滑移现象;其循环形变行为和饱和位错结构都与相邻的双滑移或多滑移晶体有许多相似之处.
关键词 单晶位向循环形变位错组态多滑移    
Abstract:Cyclic stress-strain responses and dislocation structures of copper sin-gle crystals with various tensile axes were systematically studied and comparedwith each other. Experimental results reveal that the evolution of microscopicdislocation configurations in a crystal and, accordingly, its macroscopic cyclicbehaviours are closely related with its orientation. Remarkable secondary slip hasbeen observed in some crystals with orientations well inside the ciystallographictriangle, which are usually considered as single-slip ones. Their cyclic behavioursand dislocation structures at saturation are similar to those of their neighbouringmulti-slip crystals. These results have constructed the experimental basis for thenewly proposed dislocation interaction model for cyclic deformation of fcc crystals,which will be described in the second part of this article.
Key wordscopper    single crystal orientation    cyclic deformation    dislocation configuration    multi-slip
