WebAug 1, 2015 · With phase-field-crystal method, the microscopic movement processes of asymmetric tilt sub-grain boundary system under applied stresses at high temperature … WebMigration recrystallization (grain-boundary migration) is the processes by which a grain grows at the expense of the neighboring grains. At low temperatures, the mobility of the grain boundary may be local, and the grain boundary may bulge into a neighboring grain with a high dislocation density and form new, smaller, independent crystals by a ...
