Simulation of the Recrystallization Textures of Al‐Alloys on the Basis of Nucleation and Growth Probability of the Various Textures Components

The recrystallization textures of cold rolled Al-alloys are simulated under the assumption of a growthselection of the typical recrystallization texture components out of a limited spectrum of preferentiallyformed nucleus orientations. The probability of nucleation is derived from the distribution of the potentialnucleus orientations which was determined by EBSD local texture analysis for the most importantnucleation sites in cold rolled commercial Al-alloys, i.e. Cube-bands, grain boundaries and second phaseparticles. If several nucleation sites are active simultaneously, the total nucleation probability iscomposed of the respective contributions of each nucleation site. The growth probability is derived froma 40° transformation of the rolling texture. The resulting recrystallization textures are simulatedby multiplying these two probability functions, i.e. the ODF of the nucleus orientations with the ODFof the 40° -transformed rolling texture.
