| 摘 要： | 采用＂中断法＂研究了取向硅钢二次再结晶过程中的异常长大行为,确定了二次再结晶发生的温度范围。通过对各温度下样品的EBSD微观取向分析,确定了缓慢升温时不同阶段晶粒尺寸及取向分布的变化;分析了二次再结晶过程中高斯取向晶粒与晶粒尺寸的关系及取向差分布;讨论了高能晶界理论、高迁移率晶界理论、表面气氛等对高斯晶粒长大的贡献。

| Abstract: | The secondary recrystallization and its temperature range of grain oriented silicon steel have been studied by the method of interrupting secondary recrystallization annealing.The evolution of grain sizes and grain orientations during the slow heating process was determined by EBSD technique.The Goss oriented grains,their grain sizes and their misorientations to the surrounding grains were analyzed.The effects of grain boundaries with high energy or high mobility and surface atmosphere on the growth of Goss... |
