High-strength and high-ductility magnesium alloy capable of being dissolved rapidly and preparation method thereof

Abstract

The invention provides a high-strength and high-ductility magnesium alloy capable of being dissolved rapidly and a preparation method thereof. The high-strength and high-ductility magnesium alloy capable of being dissolved rapidly comprises, by mass, 1.0%-22.0% of Gd, 0.001%-5.0% of Y, 0.001%-10% of Al, 0.001%-5.0% of Zn, 0.01%-1.0% of Zr, 0.0001%-1.0% of Sc, 0.01%-10.0% of Cu, 0.01%-3.0% of Li, 0.01%-3.0% of Ni, 0.01%-3.0% of Ga, 0.01%-3.0% of In, and the balance Mg and impurities, wherein the total content of Li, Ga and In is 0.1%-6.0%. The high-strength and high-ductility magnesium alloy capable of being dissolved rapidly can react with a water-soluble medium rapidly so as to be dissolved, has the mechanical strength properties of high strength and high ductility, and can meet the application requirements in various industrial fields.

Description

technical field

[0001] The invention belongs to the technical field of metal material processing, and in particular relates to a fast-dissolving high-strength and high-elongation magnesium alloy and a preparation method thereof. Background technique

[0002] In some special construction fields, such as oil and natural gas exploration, a large number of downhole mining tools, such as fracturing balls and bridge plugs, are required. These tools need to have mechanical properties that meet their application functions. Secondly, in order to improve engineering progress It also requires that these tools can be dissolved quickly after failure, without recycling, and at the same time, it can avoid the waste of resources when recycling tools.

[0003] Magnesium alloy is an alloy composed of magnesium and other elements. It is characterized by low density, high specific strength, good heat dissipation, good shock absorption, easy machining, good corrosion resistance of organic matter...
