The thermodynamic theory of dislocation/grain boundary interaction, including dislocation pileup against, absorption by, and transfer through the grain boundary, is developed for non-uniform plastic deformations in polycrystals. The case study is carried out on the boundary conditions affecting work hardening of a bicrystal subjected to plane constrained shear for three types of grain boundaries: (i) impermeable hard grain boundary, (ii) grain boundary that allows dislocation transfer without absorption, and (iii) grain boundary that absorbs dislocations and allows them to pass later.

位错/晶界相互作用的热力学理论

位错/晶界相互作用的热力学理论，包括位错对晶界的堆积、吸收和通过晶界的转移，是针对多晶中的非均匀塑性变形而发展起来的。案例研究是针对影响受平面约束剪切的双晶加工硬化的边界条件对三种晶界进行的：（i）不可渗透的硬晶界，（ii）允许位错转移而不吸收的晶界，以及（ iii) 吸收位错并允许它们稍后通过的晶界。
