将以MnS为主要抑制剂的普通取向电工钢作为实验材料,检测并分析脱碳样品的宏观织构及脱碳和随后加热至925℃时样品的微观织构,统计分析了Goss与周围晶粒的取向差分布。根据取向差原理计算了脱碳样品主要织构组分内各取向晶粒的取向差环境。结果表明,取向电工钢脱碳退火后Goss晶粒与周围晶粒的取向差分布呈现大角度特征,主要取向差分布范围为30°-45°,而非Goss晶粒与周围晶粒的取向差分布则呈现更多小角度特征。二次再结晶后,Goss晶粒与周围晶粒的取向差分布仍然以大角度特征为主。 MnS as the main inhibitor of ordinary oriented electrical steel as the experimental material to detect and analyze the macro-texture decarburization and decarburization of samples and then heated to 925 ℃ when the microstructure of the sample, a statistical analysis of the Goss and the surrounding grains Orientation difference distribution. According to the orientation difference principle, the misorientation environment of the oriented grains in the main texture components of decarbonized samples was calculated. The results show that the orientation difference between the Goss grains and the surrounding grains shows a large angle characteristic after the decarburization annealing of the oriented electrical steel, with the main orientation difference being in the range of 30 ° -45 °. The orientation difference between the non-Goss grains and the surrounding grains The distribution presents more small-angle features. After secondary recrystallization, the orientation difference between the Goss grains and the surrounding grains is still dominated by large-angle features.
