薄带连铸流程下取向硅钢粗大λ晶粒(〈100〉//ND,normal direction)的“遗传”会导致磁性能恶化.为解决这一问题，针对取向硅钢的热轧孪生行为开展研究，结果表明：凝固组织粗大的取向硅钢在650℃热轧时可产生大量{112}〈111〉形变孪晶，这与具有高层错能的硅钢在较高温度下难以孪生变形的传统认知不同.热轧过程中复杂的应力状态降低了变形孪晶的取向依赖性，由于具有更高的储存能，孪晶界/孪晶界及孪晶界/晶界交叉点成为再结晶形核的优先位置，大大提高了常化过程中的再结晶率，受沿孪晶界应变分布及孪晶间距离的限制，沿孪晶界形核的再结晶晶粒通常呈“饼状”,最终形成以细小且取向漫散的再结晶晶粒为主的常化组织，消除了初始凝固组织中有害的粗大λ晶粒. In strip casting grain-oriented silicon steels, the inheritance of coarse λ grains(〈100〉//ND, normal direction) can deteriorate their magnetic properties. To solve the problem, twinning behaviors in strip casting grain-oriented silicon steels during hot rolling were investigated in this work. It is found that after rolling at 650 ℃, a number of {112}〈111〉deformation twins are formed in the coarse solidification microstructure of the steels, in contrast to the well-accepted view that it is diffic...
