摘要
基于采用低温加热工艺制备的高磁感取向硅钢板坯,利用EBSD技术分析了热轧、常化、冷轧和初次再结晶阶段织构的主要组成和Goss织构的分布。结果表明,热轧板的表层是高斯织构的起源,在过渡区{100}、{110}和{111}三种面织构都有一定的占比,中心形变区域占比最多的是{100}<110>立方织构。常化板的表层存在较多的{110}<112>黄铜织构和{110}<001>Goss织构,过渡区和中心形变区都有较多的{114}<418>织构,中心形变区占比最多的是{112}<110>α线织构。冷轧织构以{112}<110>α织构为主,还有较多的{100}<110>织构。经过脱碳退火和渗氮工艺后,初次再结晶以{114}<418>织构和{111}<112>γ线织构为主。
Taking a high magnetic oriented silicon steel slab prepared under low temperature heating process as starting material,the main composition of texture and the Goss texture distribution in hot⁃rolling,normalizing,cold rolling and primary recrystallization stages were analyzed by using EBSD technology.The results show that the surface layer of hot⁃rolled sheet is the origin of Goss texture,and in the transition zone,the{100},{110}and{111}plane textures have a certain proportion,and the{100}<110>cubic texture accounts for the largest proportion of central deformation zone.There are more{110}<112>brass texture and{110}<001>Goss texture on the surface of the normalized sheet,and there are more{114}<418>oriented textures in the transition zone and the central deformation zone,and{112}<110>αlinear texture accounts for the largest proportion in the central deformation zone.The cold rolled texture is dominant by{112}<110>αtexture,though there are many{100}<110>textures.After decarburization annealing and nitriding,the primary recrystallization texture is dominant by both of the{114}<418>oriented texture and{111}<112>γlinear texture.
