铁硅合金初次再结晶对立方织构形成的影响邱振伟1,周采1,骆靓鉴1(1.上海市上海大学材料研究所)摘 要:Fe-3.2%Si合金通过真空退火发生二次再结晶,最终可形成立方织构电工钢.其中初次再结晶后的晶粒是发生二次再结晶的晶核.通过电子背散射衍射(EBSD)技术和取向成像显微(OIM)技术研究了硅钢初次再结晶对最终立方织构形成的影响.通过冷轧压下量70%和不同退火温度的工艺处理,研究了退火温度对初次再结晶的影响;发现在低温650℃下初次再结晶,形成的初次再结晶晶核有利于最终形成立方织构.关键词:Fe......

technology. The results show that, after the optimized recrystallization annealing method, the cube texture content (<10°) as high as 97.2% and the fraction of small angle (<10°) grain boundaries as high as 80.8% are obtained in the Ni12V tape. The hot rolling before cold rolling is effective to improve the cube texture content, which is expected to provide a theoretical basis for fabricating other......

退火温度对电工钢立方织构和晶界特征分布的影响周采1,邱振伟1,王辉1,骆靚鉴1(1.上海市上海大学材料研究所)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......
