| 摘 要： | 采用透射电镜研究了含锡取向硅钢高温二次再结晶退火过程中抑制剂的析出行为,分析了抑制剂对初次再结晶的抑制作用。结果表明,析出物除了常规的AlN和MnS外,还有少量Sn单质;其中AlN和MnS相是主要抑制剂,具有强烈的抑制作用;少量Sn相起辅助抑制作用,控制析出物AlN的尺寸和数量,有助于主抑制剂的弥散分布。抑制剂在600~700 ℃时开始析出长大,900 ℃显著长大,1020 ℃平均尺寸达到最大值;抑制剂的尺寸随退火温度升高而增大,体积分数、分布密度则先增大后减少。当退火温度达到1000 ℃时,析出物平均粒径约50.3 nm,体积分数最大约3.81%,分布密度约5.9×1014 个/cm3。根据试验和Zener因子综合判定抑制力,Zener因子随退火温度升高而增加,在900 ℃达到最大139,析出物分布密度达到最大8.9×1014个/cm3;在1020 ℃时,Zener因子几乎为零,完成二次再结晶过程。

| Abstract: | The precipitation behavior of inhibitor during high temperature secondary recrystallization annealing of tin-oriented silicon steel was studied by means of transmission electron microscopy (TEM), and the inhibitory effect of the inhibitor on primary recrystallization was analyzed. The results show that in addition to the conventional AlN and MnS precipitates, the precipitates also have a small amount of Sn. AlN and MnS precipitates are the main inhibitors, which have strong inhibitory effect. The Sn has an auxiliary inhibition effect, controlling the size and quantity of AlN precipitates and contributing to the distribution of main inhibitors. These inhibitors begin to precipitate at 600-700 ℃, significantly grows at 900 ℃, and the average size reaches the maximum at 1020 ℃. With the increase of annealing temperature, the size of the inhibitor increases, while the volume fraction and distribution density increase first and then decrease. When the annealing temperature reaches 1000 ℃, the average size of precipitates is about 50.3 nm, the maximum volume fraction is about 3.81%, and the distribution density is about 5.9×1014 particle/cm3. The inhibition force is comprehensively determined according to the test and Zener factor. Zener factor increases with the increase of annealing temperature, reaches the maximum 139 at 900 ℃, and the distribution density of precipitates reaches the maximum of 8.9×1014 particle/cm3. At 1020 ℃, the Zener factor is almost zero and the secondary recrystallization process is completed. |
