Abstract

The invention relates to the field of metal materials, in particular to a high-strength magnesium alloy capable of quickly reacting with media and a preparation method thereof. The high-strength magnesium alloy capable of quickly reacting with media is prepared from the following components: gadolinium, yttrium, aluminum, zinc, zirconium, rhenium, silicon, copper, iron, nickel, gallium, indium, beryllium, calcium and magnesium. Mixed reaction promoting elements (MRAE) including Si, Ni, Ga, In and the like are added to a magnesium alloy, and the continuity of magnesium hydrate can be damaged byphases formed by the elements and magnesium during reaction of magnesium and media, so that the effect that the reaction of magnesium and media is promoted is achieved; the proportion of all elementsin magnesium alloy is adjusted and controlled, so that the reaction rate of magnesium alloy and media is adjusted, thus, the controllable range is wide, additionally, the magnesium alloy material hasflexibility, and therefore, the magnesium alloy satisfies the application requirements of the industrial field.

Description

technical field [0001] The invention relates to the field of metal materials, in particular to a high-strength magnesium alloy that reacts quickly with a medium and a preparation method thereof. Background technique [0002] Magnesium alloy is an alloy composed of magnesium and other elements. Its characteristics are: low density (about 1.8g / cm3 magnesium alloy), high specific strength, large specific elastic modulus, good heat dissipation, good shock absorption, greater impact load capacity than aluminum alloy, and corrosion resistance of organic matter and alkali it is good. It is widely used in various industrial fields, mainly used in aviation, aerospace, transportation, chemical industry, rocket and other industrial sectors. It is the lightest metal among practical metals. The specific gravity of magnesium is about 2 / 3 of that of aluminum and 1 / 4 of that of iron. It is the lightest metal among practical metals, with high strength and high rigidity. On the other hand...
