通过对3%Si CGO硅钢进行恒变形速率、不同变形温度下的单道次压缩实验,结合Thermal-Calc软件,金相分析,SEM及EBSD技术,研究了取向硅钢热变形过程中组织和微观织构的变化规律。结果表明:实验钢是在双相区变形,变形后组织主要是铁素体和少量的珠光体。随变形温度的升高,晶粒由长条状变为等轴状,尺寸逐渐变大;CGO硅钢在热变形过程中立方{100}<001>取向是较为稳定存在的。随着变形温度的提高,{111}<110>等取向逐渐转向{110}<1 10>取向,且{110}<1 10>取向逐渐变得锋锐。
Through the experiments of 3% Si CGO silicon steel at constant deformation rate, single pass compression at different deformation temperatures and thermal-calc software, metallographic analysis, SEM and EBSD techniques, the microstructure and microstructure of the silicon steel during hot deformation were studied. Structure of the law of change. The results show that the experimental steel is deformed in the two-phase zone, and the deformed microstructure is mainly composed of ferrite and a small amount of pearlite. With the increase of deformation temperature, the grains change from long strip to equiaxed strip, and the size gradually becomes larger. The cubic {100} <001> orientation of CGO silicon steel is relatively stable during thermal deformation. With the increase of the deformation temperature, the orientation of {111} <110> gradually turns to {110} <1 10> orientation, and the {110} <1 10> orientation gradually becomes sharp.
