摘要
采用光学显微镜(OM)、电子背散射衍射分析(EBSD),研究了不同终轧温度下高强无取向电工钢的热轧和常化组织与织构。结果表明,终轧温度高则热轧板晶粒聚集长大的倾向性越强,发生动态再结晶的能力就强,晶粒越粗大;终轧温度低时,热轧过程中产生更大的形变储存能在常化过程中得到释放,再结晶能力更强;热轧板沿厚度方向,表层的织构主要为高斯织构({110}<001>),中心层主要为旋转立方织构({001}<110>)。常化板沿厚度方向织构基本对应热轧板,终轧温度升高有利织构占比增加。
Microstructure and texture of the high strength non-oriented electrical steel hot rolled at different finish rolling temperatures and normalized were studied by means of optical microscope(OM)and electron backscattering diffraction analysis(EBSD).The results show that the higher the finish rolling temperature of the hot rolled plate,the stronger the tendency of grain aggregation and growth,the stronger the dynamic recrystallization ability,the coarser the grains.When the finish rolling temperature is low,the deformation stored energy generated during hot rolling process is released during normalization process,and the recrystallization ability is stronger.Along the thickness direction,the surface texture of the hot rolled plate is mainly Goss texture({110}<001>),and the center layer is mainly rotating cubic texture({001}<110>).The texture of the normalized plate corresponds to that of the hot rolled plate,and with the increase of finish rolling temperature,the proportion of favorable texture raises.
