ON THE FORMATION OF RECRYSTALLIZATION TEXTURES IN BINARY Al-1.3/100 Mn INVESTIGATED BY MEANS OF LOCAL TEXTURE ANALYSIS

摘要

The development of the recrystallization textures of high purity Al-1.3/100 Mn is analysed with dependence on the degree of deformation, the annealing temperature and, particularly, the precipitation state prior to deformation. Besides X-ray macrotexture analysis, local orientation measurements by electron diffraction in a SEM (EBSD) and in a TEM (MBED) are applied. A combination of these three techniques permits orientation determination with increasing spatial resolution and yields a much more fundamental understanding about the underlying recrystallization mechanisms than is possible using solely one of these techniques.
