摘要
以实验室熔炼的3.2%Si电工钢板为原料,辅助电子背散射衍射(EBSD)技术,研究了在不同最终退火温度下,电工钢中立方织构和晶界特征分布的变化情况。结果表明,随着退火温度的升高,立方织构逐渐增强,立方取向晶粒周围的特征晶界数增多,其中Σ5晶界减少,Σ5晶界是立方取向晶粒与周围其他取向晶粒存在沿〈100〉轴转动36.9°的取向关系,具有较高的可动性,因而对立方织构的形成有利;立方取向晶粒间Σ1晶界最多。
The cube texture and grain boundary character distribution in 3.2% silicon steel under different final annealing temperatures were studied by electron backscatter diffraction（EBSD） technique.The results showed that the grain boundary character distribution around the cube-oriented grain increased with rising final annealing temperature.In the formation of cube texture,the Σ5 grain boundaries decreased,which was of high-mobility due to the special misorientation of 36.9°/〈100〉between（100） grains and primaries.Cube-oriented grains were almost separated by Σ1 boundaries.
