Abstract
3% silicon-iron melted and casted in vacuum (10−4 mm Hg) was cold-rolled to various reductions between 50.0∼97.8% and each rolled specimen was annealed for 15 minutes at 600°, 800° and 950° successively. The variations of integrated intensities of (110), (200) and (112) diffraction lines in the process of successive annealing were measured by a counter-diffractometer. It has been shown that the anomalous growth of the recrystallized grains which have the (110)[001] orientation occurs in sheets reduced 60∼75% by rolling. The maximum proportion of the (110)[001] orientation can be attained on annealing 60%-rolled specimen above 800°. If the reduction is higher than 80%, the anomalous growth of (110)[001] grains cannot be observed and at 97.8% reduction no traces of this orientation could be detected. Discussions have been made on the process of the developement of the (110)[001] texture and the mechanism of nucleation in the light of the Burgers-Cahn mechanism.
