Computer Simulation of the Kinetics of Accumulation of Primary Mesodefects at Grain Boundaries and Their Junctions

Аннотация

The accumulation kinetics of rotational and shear primary mesodefects (junction disclinations, planar mesodefects) is studied by computer simulation. The mesodefect strength is shown to increase monotonically and to level off during plastic deformation. The influence of the geometry of lattice slip and the applied stress on the mesodefect strength is analyzed.
