在实验室中采用无抑制剂法制备取向硅钢,利用XRD、TEM等方法研究了冷轧和初次再结晶阶段的微观组织与织构。结果表明,冷轧板织构主要由α织构和γ织构组成;初次再结晶退火后α织构减弱,γ面织构{111}<112>增加,初次再结晶退火70 s后出现Goss织构。EBSD分析显示Goss位向晶粒大多与{111}<112>位向晶粒相邻;随退火时间的增加,Goss和{111}<112>位向晶粒均有所增加。 In the laboratory, oriented silicon steel was prepared by using inhibitor-free method. The microstructure and texture of cold-rolled and primary recrystallized phases were studied by XRD and TEM. The results show that the texture of cold-rolled sheet mainly consists of α textures and γ textures. After the first recrystallization anneal, the α textures weakened and the γ textural textures {111} <112> increased. After the initial recrystallization anneal for 70 s, Goss Texture. EBSD analysis showed that most of the Goss orientation grains were adjacent to the {111} <112> grains. With the increase of annealing time, Goss and {111} <112> grains increased toward the grains.
