摘　　要：利用X-射线衍射技术研究了Fe-3%Si取向电工钢中的铌含量-点阵畸变-织构三者之间的关系。结果表明,在一定的范围内,随着铌含量的增加,再结晶退火前的钢板内高斯晶粒的点阵畸变增加,再结晶退火后的高斯织构也相应增加,抑制剂是通过影响形变基体的微观应变而影响取向电工钢的再结晶织构的。The relationship between Nb content, lattice distortion and textures has been studied by X-ray diffraction technique in strip of Fe-3%Si grain oriented electrical steel. It was found that, the lattice distortion in strip before recrystallization annealing increased with increasing Nb, and the Goss texture in strip after recrystallization annealing increased correspondingly also in certain Nb content range. The inhibitor element Nb effected recrystallization texture in the grain oriented electrical steel by effecting micro-strain of deformation matrix.
