Моделирование формирования зоны кристаллографического сдвига в меди с учетом ориентационной зависимости

Моделирование формирования зоны кристаллографического сдвига в меди с учетом ориентационной зависимости

Abstract

The mathematical model of formation of crystallographic shear zone in FCC metals is presented. The mathematical model of formation of crystallographic shear zone in FCC metals is presented. The model allows investigate of energy, scale and temporal characteristics of the elementary crystallographic slip and the shear zone as a whole as well as of the evolution of dislocation loop. The analysis of changes in the shape of a dislocation loop, the kinetic energy per unit length of the dislocation, and the rate of expansion of a dislocation loop for different orientations at room temperature in copper was done.

Представлена математическая модель динамики формирования элементарного кристаллографического скольжения и зоны сдвига в металлах с ГЦК-структурой, позволяющая исследовать формоизменение дислокационной петли, а также энергетические, масштабные и временные характеристики элементарного кристаллографического скольжения и зоны сдвига в целом. Проведен анализ изменения формы дислокационной петли, кинетической энергии единицы длины дислокации и скорости расширения дислокационной петли по различным ориентациям в меди при комнатной температуре.
