摘　　要：通过研究不同冷轧压下率情况下冷轧和退火IF钢的纤维织构的变化曲线，得出了其织构演变主要发生在{111}／／ND、（110）／／RD、{100}／／ND、〈112）／／RD组分之间；退火时（110）／／RD组分一部分转化为{111}／／ND，一部分转化为（112）／／RD。随冷轧压下率的增加，冷轧IF钢γ纤维织构含量在80％变形率下达最大值22．6％，而退火γ纤维织构含量明显增加。当冷轧压下率超过90％时，不能得到好的γ纤维织构分布形态。By means of the quantitative research of the cold deformation and recrystallization textures of the IF steel under different deformation rate, one can obtain that the textures change main among the t111 }//ND, 〈 ll0）//RD, {I00 }//ND and 〈 ll2）//RD components; One part of the 〈ll0）//RD component transfers to { 111 I//ND, another part is 〈ll2）//RD; The max value ofT fiber texture quantitative under 80% deformation rate is 22. 6%, and the quantitative of tempering y fiber texture adds obviously. The distribution shape of y fiber texture is not ideal when the deformation rate over than 90%.
