Abstract

The invention discloses high-strength rapid-corrosion magnesium alloy and a preparation method thereof. The high-strength rapid-corrosion magnesium alloy comprises the chemical components including, by weight, 2-7% of Al, 1-2% of Zn, 0.2-0.6% of Zr, 0.1-0.3% of Si, 0.1-0.5% of Mn, 0.1-0.3% of Ca, 1-1.5% of Fe, 0.05-5% of Cu and the balance magnesium and inevitable impurities, wherein the Si and the Mn are added as intermediate alloy. The magnesium alloy has the more excellent strength, ductility, hardness and mechanical performance such as creep resistance compared with those of traditional commercial magnesium alloy and the advantage of rapid dissolution.

Description

technical field [0001] The invention relates to a magnesium alloy and a preparation method thereof, in particular to a high-strength rapid corrosion magnesium alloy and a preparation method thereof. Background technique [0002] According to the American Society for Metals (ASM), light metal materials are defined as aluminum, magnesium, titanium and their alloys. According to the analysis of the material characteristics of these three light metals, it can be found that light alloy materials have strong shock resistance, excellent machinability, recyclability, light weight / energy saving, anti-EMI, good corrosion resistance, and excellent engineering performance. Good performance, flexible design (integrated parts / rapid manufacturing, assembly, dismantling and recycling; diverse manufacturing processes and surface treatment application technologies), high quality / fashion sense, etc., and are widely used in transportation, aerospace, national defense, Petrochemical, energy, pa...
