Abstract:The recrystallized grain structure of Al-(Mn)-Fe-Si alloys after isothermal annealing was studied by electron backscatter diffraction (EBSD) technique. Statistical correlation suggests that the frequency of forming P-oriented ({011}á566？) grains at a particle larger than the critical diameter (about 1.1 μm) is about 2% when the effect of fine dispersoids and concurrent precipitation is negligible. The overall grain number density is correlated linearly with the number densities of P and Cube ({001}á100？) grains. The grain number densities of typical orientations (P, ND-rotated cube {001}á310？ and Cube) and the overall recrystallized grains increase as rolling strain increases, following a similar exponential law.
