Problems solved by technology

In the early days, there were patent reports on adding alloying elements such as yttrium (Y) and silicon (Si) to improve the superplastic forming and manufacturing of magnesium alloys. However, because the forming temperature must be as high as 200°C, the room temperature formability has not been greatly improved, and the manufacturing method is complicated. , cannot be universally applied
In addition, adding alloying elements such as indium (In) and silver (Ag) to magnesium can reduce the axial ratio c / a of magnesium alloys, thereby stimulating non-basal plane slip, which in turn can improve room temperature plasticity, but these elements are expensive Expensive element, not suitable for large-scale applications

Abstract

The invention discloses a high-room-temperature ductility magnesium alloy material and a preparation method thereof. The magnesium alloy material comprises, by weight, 1.0%-5.0% of Li, 2.5%-3.5% of Al, 0.7%-1.3% of Zn, 0.2%-0.5% of Mn, no more than 0.3% of impurities, and the balance Mg. The preparation method comprises that under the condition of vacuumizing and inert gas leading-in, pure lithium and an AZ31 magnesium alloy, which are in a formula ratio are heated to 720 DEG C, when the alloy is melted completely, the alloy is subjected to heat preservation and storage at the temperature of 700 DEG C for 15min, and then the melted alloy liquid is poured into a mold. According to the method, Li elements are added into the AZ31 magnesium alloy, the obtained magnesium alloy material has high room-temperature ductility, and the anisotropy degree is low. Besides, the added alloy elements are low in cost relatively and simple in preparation process.

Description

technical field [0001] The invention relates to a magnesium alloy material and a preparation method thereof, in particular to a high room temperature plastic magnesium alloy material and a preparation method thereof. Background technique [0002] Magnesium alloy has the advantages of low density, high strength, high thermal conductivity, battery shielding, and easy recycling. In recent years, it has been gradually used as a lightweight structural material in the fields of transportation, communications, electronics, aerospace, and other civilian products. Deformed magnesium alloys are usually deformed by extrusion, rolling, forging and other deformation methods to improve the microstructure of the alloy and improve the performance of the magnesium alloy. Magnesium alloy has the characteristics of hexagonal crystal structure, and there are few independent slip systems under room temperature deformation conditions, resulting in low room temperature plasticity and difficulty in...
