The effect of phase transformations on the recrystallization texture of cold-rolled steel

Abstract

The texture changes in cold-rolled steels with various degrees of reduction before and after heating them below and above the critical points Ac₁ and Ac₃, have been investigated by a magnetometric method. It is shown that at annealing temperatures above the Ac₃ point the sharpness of the recrystallization texture in general diminishes. The recrystallization texture of the first kind with negative amplitudes A₄ of the normal component of the magnetization vector (of the type {110} 〈001〉 with corresponding scattering) scarcely emerges as the dominant texture at such preliminary reductions as are obtained by cold rolling. This is due to the high-temperature heating of the iron in the γ-phase.
