摘　　要：采用OM、EBSD检测分析技术研究了铌对低温取向硅钢热轧组织与织构的影响,探索是否应在低温取向硅钢中加入铌。结果表明,含铌相较于不含铌取向硅钢热轧板晶粒更加细小,沿板厚方向组织梯度更加明显;铌元素的加入优化了取向硅钢热轧板织构,含铌比不含铌取向硅钢热轧板中的旋转立方织构取向密度小,而高斯织构和γ取向线密度大,其中高斯织构{110}<001>的织构密度f(g)高达12.19。The effect of niobium on the microstructure and texture of low temperature oriented silicon steel was studied by OM and EBSD. The results show that the grain size of Nb-bearing hot rolled sheet is finer than that of Nb free oriented silicon steel, and the microstructure gradient along the thickness direction is more obvious. The addition of Nb optimizes the texture of hot rolled silicon steel. The rotated cubic texture orientation density of the oriented silicon steel hot-rolled sheet is small, while the Goss texture and γ-oriented linear density are high. And the texture density of the Goss texture{110}<001> is as high as 12.19.
