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.
