摘要(Abstract)：

在实验室条件下模拟CSP(Compact Strip Production)热轧板为基板生产的低碳冷轧板罩式退火过程,研究再结晶阶段加热速度对冷轧板罩式退火过程晶界特征分布的影响。结果表明,在退火过程再结晶阶段加热速度为40℃/h的试样具有均匀的饼形晶粒组织,较高比例的{111}<110>和{111}<112>取向的晶粒。加热速度为40℃/h的试样含有的Σ3、Σ9、Σ13b晶界的比例高于加热速度为30℃/h的试样,Σ11晶界的比例则低于加热速度为30℃/h的试样。Σ3晶界随相邻同类型取向的增加而增多,Σ11晶界比例低时{001}<110>取向晶粒比例低、Σ13b晶界比例高时{111}取向晶粒比例高。
