High-strength deformed magnesium alloy plate with low anisotropy at room temperature and preparation method thereof

Abstract

The application relates to a preparation method of high-strength deformed magnesium alloy plate with low anisotropy at room temperature, which comprises a magnesium alloy ingot smelting step, an ingot solid solution treatment step, a hot extrusion breakdown step, a multiple one-way room-temperature rolling step and an aging heat treatment step, has the advantages of low cost, simple process flow and the like by using conventional equipment, and is very suitable for large-scale industrial application. The application also provides the high-strength deformed magnesium alloy plate with low anisotropy at room temperature obtained by the preparation method. The application fully plays the advantages of combined addition of Nd and Gd elements, and realizes high strength and low anisotropy of the plate at room temperature through the process provided by the application, and the comprehensive mechanical properties are obviously better than those of other magnesium rare earth alloy plates with similar rare earth addition amount and preparation cost.
