本文简要地介绍了目前广泛采用的几种晶界结构理论,并以此为基础从宏观与微观相结合的角度阐述了不同结构的晶界在循环形变与单向形变中,与晶内滑移位错的交互作用。
In this paper, we briefly introduce several widely used theories of grain boundary structure, and based on this, we describe the relationship between the grain boundaries of different structures in cyclic deformation and unidirectional deformation from the perspective of macroscopic and microscopic. Dislocation interaction.
