文摘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}?566?) 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}?100?) grains.
