of this tape and its essential characterizations were presented. The influence of hot rolling process before the large deformation on deformation texture of initial ingots was investigated by rolling... 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......
轧制方向对Fe-3%Si合金织构演变规律的影响颜孟奇1,杨平1,蒋奇武2,付勇军1,毛卫民2(1.北京市北京科技大学材料科学与工程学院2.鞍钢股份有限公司 冷轧硅钢厂)摘 要:形成锋锐的Goss织构是取向硅钢获得优异磁性能的关键,初始样品表层中较强的Goss织构对最终的强Goss织构起重要作用.本文通过改变硅钢冷轧方向获得不同的初始织构及初始组织,考察热轧板表层及中心层不同的组织及织构的进一步变化对一次冷轧,中间退火,二次冷轧及脱碳退火,二次再结晶退火后的织构及组织变化规律的影响.探讨了这些特殊方式制备的样品中......
