DYNAMICAL ANALYSIS ON THE FORMATION OF DISLOCATION PATTERN IN THE EASY SLIP STAGE OF SINGLE CRYSTALS 1
单晶易滑移阶段位错结构形成的动力学分析

The mechanism governing the conservative climb of dipoles and a new dislocation dynamic model for single slip are proposed. Using this model, the formation of the carpet that is a planar array structure in the I stage of crystal hardening is predicted, in agreement with the experimental results. The present model takes into account not only the drift and climb mechanism of dipoles but also the three-dimensional movement of plus and mines mobile dislocations through slipping and cross-slipping. Besides, the ...
