Abstract:

Single crystals of 3%Si-Fe alloy have been used for a study of the formation of rolling and annealing textures. It is known that when a 3%Si-Fe (110)[001] single crystal is cold rolled, (110)[001] decreases and the crystal rotation towards (111)[112] occurs, and upon annealing after 70% cold reduction it recrystallizes back to its original (110)[001] orientation.
The present insestigation aimed at clarifying the relationship between the residual (110)[001] component in the deformed texture and the recrystallized (110)[001] texture through microscopic observation, X-ray stress measurement, hardness measurement and electron microscopic observation.
The (110)[001] component is preserved as a minor component between deformation bands rotated towards a (111)[11 2] orientation. The hardness and stress measured by X-ray are always larger in the (110)[001] component than in the components rotated towards (111)[11 2]. On annealing, the (110)[001] component is shown to recover earlier than the rotated components in the 70% deformed crystal. However, under 60% deformation, the (110)[001] component is slower in recovery than rotated components.
Recrystalized grains appeared at or contiguous to the boundaries of deformation bands where (110)[001] seems to have been preserved. From these facts, it is concluded that the most strained component, namely the (110)[001] component, in the deformed texture leads to the (110)[001] recrystallized texture in the 70% cold-rolled (110)[001] single crystal.
