Problems solved by technology

However, the above two processes are too complicated compared with ordinary extrusion and rolling processes, which increases the cost to a certain extent, and cannot be widely used
[0004] Another way to improve the plasticity and anisotropy of magnesium alloys is to add alloying elements. Studies have shown that adding rare earth elements can improve the basal texture of magnesium alloys, but the improvement is not large, and the price of rare earth elements is generally lower than that of magnesium alloys. high

Abstract

The invention discloses a low anisotropic magnesium alloy material and a preparation method thereof. The low anisotropic magnetic alloy material comprises the following components in percentages by weight: 1.0% of Li, 2.5-3.5% of Al, 0.7-1.3% of Zn, 0.2-0.8% of Mn, 0.3% of Al-5Ti-1B, not more than 0.3% of impurity and the balance of magnesium. The preparation method comprises the following steps of: heating pure lithium at a formula amount, an Al-5Ti-1B intermediate alloy and an AZ31 magnesium alloy to 720 DEG C under the conditions of vacuum and inert gas, after completely smelting the alloy, thermally insulating at 700 DEG C and standing for 15 minutes, and pouring the smelted alloy into a mold. According to the invention, the Li and the Al-5Ti-1B intermediate alloy are added in the AZ31 magnesium alloy, so that the intensity of a magnesium alloy basal plan texture is reduced, the anisotropy of the magnetism alloy is reduced, grains are refined, and the mechanical property of the magnesium alloy is improved.

Description

Technical field [0001] The invention involves a magnesium alloy material and its preparation method, which specializes in a low -oriented heterosexual magnesium alloy material and its preparation methods. Background technique [0002] Magnesium alloy has the advantages of low density, high strength, high heat conductivity, battery shielding, and easy recycling. In recent years, as light -quality structural materials, it has been gradually used in the fields of transportation, communication, electronics, aerospace and other civil products.Transformers usually improve the organizational structure of the alloy by squeezing, rolling, and forging, and improve the performance of magnesium alloy.Magnesium alloys have the characteristics of densely rowing hexagonal crystals. They have less independent sliding system under room temperature deformation conditions, resulting in low plasticity of room temperature and difficulty in deformation processing. It has become a bottleneck that hinde...
