Abstract: Structure and texture orientation of 50W600 cold rolled non-orientation electrical steel(0.003~0.008C,0.3Si)during annealing at 700~760 ℃ for 3~360 s,water cooling have been studied by metallography and electron back-scattering spectrum difraction analysis.Results showed that incrensing annealing temperature the rate of recrystaliza-tion and grain size increased; during annealing at 740 ℃,as annealing time increased from 10 s to 360 s,the rate of recrys-tallization increased from 22.5% to 100% and average grain size increased from 3.08 μm to 17.17 μm,and the density of recrystallization texture at α- fibre decreased,as annealing for 15 s the density of {001}〈110〉,{112}〈110〉,{111}〈110〉 and {110}〈110〉was abot 1.5 and the density of {111}〈011〉 and {111}〈112〉at γ-fibre was steadily about 0.25.
摘要: 通过金相和电子背散射衍射法(EBSD)研究50W600冷轧无取向电工钢(0.003%~0.008%C、0.3% Si)在700~760℃3~360s退火水冷时的组织和织构取向演变。结果表明,随退火温度的提高,钢的再结晶率和 晶粒尺寸增大,740℃退火时,当保温时间由10s增加至360s,再结晶率由22.5%提高到100%,平均晶粒尺寸由 3.08μm增大至17.17μm。同时再结晶织构α线的取向密度下降,在15s时[001}<110〉、{1121<110〉、{1111 <110〉、{110〈110〉的取向密度均为1.5左右,y线上{111}<011〉和{111}〈112〉的取向密度稳定在0.25左右。
