| 摘 要： | 为对双辊连铸硅钢薄带的后续处理工艺提供理论依据和技术支持,用光镜、透射电镜和能谱分析等方法研究硅含量变化对薄带组织的影响.硅钢薄带的质量分数分别为0.5%,1.0%,3.0%,4.5%和6.5%.结果表明:硅含量对硅钢薄带组织的晶粒尺寸、晶界形貌和晶内位错等均有显著影响.当硅的质量分数为3.0%~4.5%时,薄带晶粒较大,晶界较纯净,晶内位错量和成分偏析较少.

| Abstract: | The effects of Si concentration on microstructure of Si steel thin strips prepared by twin roll continuous casting were investigated with optical microscopy,transmission electron microscopy and energy spectrum analysis to provide a theoretical and technological reference for post treatment procedure of the steel.The Si steel under investigation has Si concentration of 0.5%,1.0%,3.0%,4.5% and 6.5%(mass fraction),respectively.The results show that Si concentration strongly affects grain sizes,morphology of gr... |
