摘　　要：以实验室模拟CSP工艺生产的Fe-3%Si钢为研究对象,采用XRD、EBSD技术研究了取向硅钢初次再结晶晶粒的取向和晶界结构。结果表明,初次再结晶晶粒中,高斯晶粒在数量上并不占优,优势取向为γ取向。高斯晶粒主要出现在{111}<112>取向晶粒周围,且高斯晶粒周围的晶界类型以25°～55°的大角度晶界和Σ3晶界为主。Grain orientation and grain boundary structure of the primary reerystallization annealed samples of Fe-3% Si steel produced by CSP teehnology simulated in laboratory conditions were investigated by XRD and EBSD technique. The results show that Goss grains are not dominant in quantity and the dominant orientation is γ texture for primary reerystallization grains. Goss grains are mainly nucleated around {111} （112）grains and they are mainly large angle grain boundaries from 25°to 55° and ∑3 grain boundaries.
