Abstract

Provided is a refined Goss-grain aluminum alloy plate and a preparation method thereof. The refined Goss-grain aluminum alloy plate includes the following compositions: 3.7-4.8 wt % of Cu, 1.2-1.7 wt % of Mg, 0.3-0.8 wt % of Mn, 0.03-0.10 wt % of Ti, and the balance of Al. The refined Goss-grain aluminum alloy plate is prepared by a method including subjecting an Al—Cu—Mg alloy ingot with a certain composition to a homogenizing at a temperature of 470-505° C., a hot rolling at high temperature of 465-495° C. with a large deformation of 80%-98% and a high final temperature, then directly to a cold rolling with a small or medium deformation of 5% to 50%, and then to a recrystallization and annealing treatment at a temperature of 300-450° C., a solid solution treatment at a temperature of 460-505° C., and a natural aging treatment for at least 96 hours.
