It was shown that dislocation unpinning, motion, and multiplication in crystals during testing at stressing rates of 0.0001 to 35MPa/s and homologous temperatures ranging from 0.001 to 0.945, led to the consecutive formation of sub-grain walls, cells, and grain boundaries with increasing stressing rate. The scaling behavior of the dislocation mean paths at multiplication, their spacing in slip-lines and the appearance of various high-density dislocation structures as a function of the reciprocal of the applied stress, confirmed the pivotal role which was played by dislocation cross-slip, climb, and Orowan bowing in the evolution of deformation structures in various classes of crystal.
