摘　　要：总结了近年来冷轧无取向硅钢再结晶组织和织构演变的研究进展,重点总结了快速加热条件下再结晶组织和织构的研究进展。快速加热抑制回复,使再结晶发生前的剩余形变储能增加,导致形核驱动力增加并促进大角晶界迁移,因而使形核率增加、晶粒细化。同时,快速加热降低了晶核择优位向,最终降低了〈111〉//ND再结晶织构组分强度。The purpose of this review is to bring together the evolution of structure and texture during annea ling in cold-rolled non-oriented silicon steel, special attention is given to the effect of rapid heating annealing on the de- velopment of recrystallized structure. Rapid heating reduces the release of stored elastic energy during recovery and makes the preserved cold-rolled stored elastic energy before recrystallization increase, which enhances the driving force for grains nucleation and promotes high angle grain boundaries migration, thereby increasing nucleation rate and lea- ding to grain refining. Meanwhile, rapid heating lowers the orientation dependence on the recrystallization nucleation, and finally decreases the （111）//ND texture component intensity.
