中文摘要：

研究了取向硅钢制备过程中常见的两种冷轧工艺，主要研究了一阶段冷轧与两阶段冷轧＋中间退火工艺对初次再结晶组织及织构的影响．结果表明：采用两阶段冷轧＋中间退火工艺制备以Cu2S为主抑制剂的取向硅钢，其初次再结晶平均晶粒尺寸为18．1μm，高斯晶粒的体积分数为0．6％，迁移性强的重位点阵晶界（∑5＋∑9）和高能晶界（20°-45°取向偏差角）所占比例分别为1．8％和50．4％．与一阶段冷轧工艺相比，其初次再结晶晶粒较细，且高斯晶核与特征晶界所占的比例较高，有利于高斯晶粒发生二次再结晶．

英文摘要：

Two common cold-rolling processes of grain oriented silicon steel and the effects of the single stage cold rolling and two-stage cold rolling with intermediate annealing processes on the primary recrystallization microstructure and texture were investigated. The results revealed that for the grain oriented silicon steel prepared under the two-stage cold rolling process with intermediate annealing with CuE S as the main inhibitor, the average grain size of the primary recrystallization microstructure was 18.1 μm, the volume fraction of Goss grain was 0. 6% , the ratio of coincidence site lattice （CSL, ∑ 5 ＋ ∑9 ）and high energy grain boundaries （20 ~ 45° misorientation angles ）which have the higher migration than the conventional boundaries were 1.8% and 50.4% , respectively. Compared with the single stage cold rolling process, the primary recrystallization grains of the two-stage cold rolling with intermediate annealing were finer; moreover, the proportion of Goss grain and high migration boundaries were larger, which were favorable to the secondary recrystallization occurrence of the Goss grain.
