摘要/Abstract

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。

关键词: 高磁感取向硅钢, 低温加热, 织构

Abstract: 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> α linear texture accounts for the largest proportion in the central deformation zone. The cold rolled texture is dominant by {112}<110> α texture, 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> γ linear texture.

Key words: high magnetic induction oriented silicon steel, low temperature heating, orientation texture
