摘要

摘要: 對低溫加熱工藝生產的以AlN為主抑制劑的高磁感取向硅鋼高溫退火過程進行中斷實驗，借助電子背散射衍射技術對高溫退火過程中高斯晶粒的演變進行了研究.在升溫過程中高斯晶粒平均尺寸先減小再增大.800℃時取向分布函數圖出現高斯織構組分，但強度很弱，高斯晶粒偏離角在10o以上；900℃時高斯晶粒平均生長速率超過其他晶粒；950~1000℃時高斯晶粒異常長大，偏離角3o~6o；在1000℃之前高斯取向晶粒相比于其他晶粒沒有尺寸優勢.

Abstract: The high-temperature annealing process of high permeability grain-oriented silicon steel with AlN as an inhibitor was studied by interrupting test. The evolution of Goss texture in this process was analyzed by electron back-scattered diffraction. It is found that the Goss grain size first decreases and then increases with the rise of temperature. Goss texture appears in the orientation distribution function at 800℃, but the intensity is very weak and the deviation angle is more than 10o. The average growth rate of Goss grains is faster than other grains at 900℃. Goss grains grow abnormally from 950 to 1000℃, and the deviation angle ranges from 3o to 6o. Before 1000℃, in comparison with other grains, Goss grains have no size advantage.
