摘要

提出了由多晶非均匀塑性变形引起的晶界平面剪切细观缺陷的可调节塑性变形和弹性能松弛模型。结果表明，这一过程可以通过中缺陷的连续分裂和位错壁进入晶体内来实现。关键词:晶界，中缺陷，调节塑性变形，滑移带

Model of accommodation of planar shear mesodefect

A model of accommodative plastic deformation and relaxation of elastic energy of planar shear mesodefects at grain boundaries resulting from inhomogeneous plastic deformation of polycrystals is proposed. It is shown that this process can be carried out by sequential splitting off from the mesodefect and leaving dislocation walls into the grain body. Keywords: grain boundary, mesodefect, accommodation plastic deformation, slip band
