Method for continuous production of magnesium alloy strip basal plane texture through corrugated pre-rolling weakening

Abstract

The invention belongs to the technical field of metal machining, and discloses a method for continuously producing of magnesium alloy strip basal plane texture through corrugated pre-rolling weakening. The method comprises the following steps that firstly, the method is used for carrying out corrugated rolling on the magnesium alloy strip, local strain is introduced, and the subsequent traditionalflat binding is carried out. The rolling process of the method comprises the following steps of (1) enabling the original magnesium alloy strip to pass through a corrugated roller, and rolling the original magnesium alloy strip into a wavy shape; and (2) enabling a corrugated strip to bite into a subsequent flat roller, and rolling the corrugated strip into a flat strip with the required thickness through the flat roller. The magnesium alloy strip prepared by the method has the advantages that the Schmid factor of the magnesium alloy strip is increased, the activity of the non-basal plane sliding system including the mechanical twin crystal is remarkably promoted, continuous arc grooves of the magnesium alloy strip can control the evolution of tissue and texture, the elongation at break is improved, the texture strength of the basal plane is weakened, and the comprehensive performance required by production is met. In addition, the forming rate of the magnesium alloy cold strip is improved, the process is simple, and the rolling productivity of equipment is high.

Description
