THE COLD-ROLLING AND RECRYSTALLIZATION TEXTURES OF IRON-SILICON SINGLE CRYSTALS

The cold-rolling and recrystallization textures of Fe-Si (3.25% Si) single crystals with orientations close to (110) [001], (320) [001] and (110) [1(?)2] were investigated. As the reduction increased from 60 to 85 pct, for lower rates of reduction, the recrystallization texture of (110) [001] single crystal changed gradually from the (110) [001] to (310) [001] orientation, but it remained in the (110) [001] orientation in the case of higher rates of reduction. The behavior of the (320) [001] single crystal during coldrolling was similar to the (110) [001] single crystal, whereas in the (110) [1(?)2] single crystal the rate of reduction showed no pronounced effect on the recrystallization texture.These results were discussed according to the theory of recrystallization in situ, and the change of recrystallization textures with reduction rates can be explained satisfactorily.
