Abstract

Abstract

The mechanism of recrystallized texture evolution of non-oriented silicon steel during grain growth has been studied by using EBSD technology.The results show that texture evolution during recrystallized grain growth originates from different growth rates of texture components;grain size is not the only determinant for the grain growth,and the misorientation angle distribution of the grain and other surrounding grains has obvious influence on its growth.Thanks to grain competition between {111} ＜112＞ and {111} ＜110＞,sharpness of {111} texture’s orientation changes alternately.As the annealing time increases at 950 ℃,the {100} ＜120＞ texture and {100} ＜310＞ texture are weakened while {110} ＜001＞ is enhanced;As the annealing temperature increases with a constant annealing time for 3.5 min,all of the {110} ＜001＞,{100} ＜120＞,and {100} ＜310＞ textures are enhanced.Temperature has a great impact on misorientation angle distribution of grains with different orientations.
