Abstract

Two commercial Aluminium alloys with high Mn content were investigated in three different precipitation states. The rolling textures possess a portion of random orientations that is proportional to the volume fraction of larger particles. It is therefore identified with their deformation zones having about double the diameter of the particles. The recrystallization textures are weak for high annealing temperatures and show the more retained rolling texture the more the temperature is lowered. This is interpreted as a matter of nucleation site. But also growth mechanisms influence the texture evolution. Minor texture components are characteristic for the different conditions.
