本文用X射线研究了含MnS的一般取向硅钢和含AIN+MnS的高磁感取向硅钢的形变和再结晶织构;测定了形变态不同位向的晶格畸变贮能;并且计算了形变、再结晶织构转变的位向关系。 根据贮能差和位向差共同控制织构转变的模型,以及晶界迁动理论、推导了退火时织构转变的模式和数学关系式。理论的分析定性地说明了实验结果。可以认为:取向硅钢形变和再结晶织构转变主要是受贮能差和位向差共同控制的择优长大过程。
In this paper, the deformation and recrystallization texture of general oriented silicon steel containing MnS and high magnetic induction oriented silicon steel containing AIN + MnS were studied by X-ray; the lattice distortion energy storage in different orientations of deformation state was measured; and the deformation, Recrystallization texture change the direction of the relationship. According to the model that the energy storage difference and the orientation difference jointly control the texture transition, and the grain boundary migration theory, the mode and mathematical relation of the texture transition during annealing are deduced. Theoretical analysis qualitatively illustrates the experimental results. It can be considered that the deformation and recrystallization texture of oriented silicon steel is mainly controlled by the difference of energy storage and orientation.
