The effect of Ce element on the evolution of recrystallization texture in a 1.2%Si-0.4% Al non-oriented electrical steel during annealing process was investigated by using OM, SEM/EBSD and OIM software. The results showed that the recrystallized grain size and recrystallization ratio of specimens containing Ce are coarser and higher than those of specimens without Ce respectively. The fraction of favourable textures in specimens with Ce during recrystallization is also higher than those in specimens without Ce. Moreover, the fraction of unfavorable {111} texture in specimens with Ce is very less. Appropriate Ce in non-oriented electrical steel purified steel, reduced fine MnS, coarsen and modified Al2O3 and spherified AIN inclusions. This result in more favorable textures appeared in non -oriented electrical steel containing Ce.
