Abstract

The invention provides a high-performance alkenyl magnesium alloy material which mainly comprises the following components in percentage by mass: 5-8% of graphene substances, 1-2% of Co, 1-2% of Y, 4-7% of Al, 1-3% of Mn, 0.2-0.8% of Li, 0.2-1.0% of Zr, 0.1-0.5% of Ca, 0.1-0.5% of Zn, 0.2-1.0% of Cd, 0.3-0.7% of Yb, 0.3-0.7% of Ni, 0.1-1% of Sb, 0.1-1% of Mo and the balance Mg. A preparation method for the high-performance alkenyl magnesium alloy material comprises the following steps of: pre-heating pure magnesium metal, smelting the pure magnesium metal and other raw materials containing metal elements under protection of inert gases, and preserving the temperature after smelting; and increasing the temperature after preserving the temperature, adding graphene substance raw materials, standing after uniformly stirring, and filtering to obtain a crude magnesium alloy liquid. The alkenyl magnesium alloy material provided by the invention has relatively excellent performance indexes such as heat resistance, strength and hardness.

Description

technical field [0001] The invention relates to the field of magnesium alloy processing, in particular to a high-performance ene-magnesium alloy material and a preparation method thereof. Background technique [0002] Magnesium alloy is an alloy composed of magnesium and other elements. Its characteristics are: low density (1.8g / cm 3 Magnesium alloy or so), high specific strength, large specific elastic modulus, good heat dissipation, good shock absorption, greater impact load capacity than aluminum alloy, and good corrosion resistance to organic substances and alkalis. The main alloying elements are aluminum, zinc, manganese, cerium, thorium and a small amount of zirconium or cadmium. Magnesium-aluminum alloys are currently the most widely used, followed by magnesium-manganese alloys and magnesium-zinc-zirconium alloys. Mainly used in aviation, aerospace, transportation, chemical industry, rocket and other industrial sectors. It is the lightest metal among practical met...
