The Formation of New Orientations During Recrystallization of Silver Single Crystals with {112}< 111 > Initial Orientation

摘要

The recrystallization mechanisms in high purity Ag crystals with C{112}< 111 > initial orientation, deformed by channel-die compression, have been studied by local orientation measurements using TEM and SEM/EBSD. The microtexture analysis clearly indicates the importance of a simple relation of 25-40° (< 111 > or < 112 >) type, which is frequently observed during the early stages of recrystallization between isolated nuclei of uniform orientation and one of the as-deformed groups of components. As recrystallization proceeds, recrystallization twinning increases radically. In C-oriented silver single crystals this latter mechanism also plays a decisive role in the formation of the cube orientation.
