铁硅合金(含硅3.25%)的样品,经过不同的冷轧和中间退火程序,在最后高温退火时,可以通过二次再结晶,或者一次再结晶形成集中的立方织构。通过二次再结晶形成立方织构时,并不包括重新形核的过程。(100)[001]取向的二次再结晶“晶核”,在一次再结晶完成后,就已经存在。通过一次再结晶形成的立方织构,由于样品在冷轧后,得到了较强的加工立方织构,退火时通过同位再结晶,就得到了再结晶立方织构。In the prsent paper some of the results of our studies on the formation of cube texture in an iron silicon alloy with silicon content of 3.25% are described. It is found that cube texture in this alloy can be developed either by the process of secondary recrystallization or simply by the process of primary recrystallization. In case of the formation of cube texture by the former process no nucleation process is involved. Nuclei of the (100) [001] orientation are already present after the completion of primary recrystallization, and are surrounded, for most cases, by grains having (110) [001] orientations. Exaggerated growth of cube-oriented grains takes place when the normal growth of other grains are restricted. In case of the formation of a cube texture by primary recrystallization, a spread of cold-rolled cube texture must be present after the last step of cold rolling. Upon final annealing at a low temperature, a recrystallized cube texture by the process of "recrystallization-in-situ" is obtained. The cube texture may be further concentrated with an increase of final annealing temperature.Basing upon the measurements by the conventional magnetic torque method, the amount of (100) [001] texture is calculated to be over 90%.
