Abstract

The recrystallization textures of cold rolled Al-alloys are simulated under the assumption of a growth selection of the typical recrystallization texture components out of a limited spectrum of preferentially formed nucleus orientations. The probability of nucleation is derived from the distribution of the potential nucleus orientations which was determined by EBSD local texture analysis for the most important nucleation sites in cold rolled commercial Al-alloys, i.e. Cube-bands, grain boundaries and second phase particles. If several nucleation sites are active simultaneously, the total nucleation probability is composed of the respective contributions of each nucleation site. The growth probability is derived from a 40°<111> transformation of the rolling texture. The resulting recrystallization textures are simulated by multiplying these two probability functions, i.e. the ODF of the nucleus orientations with the ODF of the 40°<111>-transformed rolling texture.
