On the formation of recrystallization textures in binary Al-1.3% Mn investigated by means of local texture analysis
- RWTH Aachen (Germany). Inst. fuer Metallkunde und Metallphysik
The development of the recrystallization textures of high purity Al-1.3% Mn is analyzed 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. The recrystallization textures are characterized by a competition between cube-oriented grains which nucleate at band-like structures and grains due to particle stimulated nucleation (PSN). The evolution of the resulting textures is discussed in terms of formation and subsequent growth of the recrystallization nuclei.
