Magnesium alloy and manufacturing method thereof

Abstract

A magnesium alloy and a manufacturing method thereof, belonging to the technical field of metal materials and heat treatment, the magnesium element, whose weight percentage is 85% of the total composition of the alloy; the lithium element, whose weight percentage is 12% of the total alloy composition; the zinc element, whose weight percentage The percentage is 2% of the total composition of the alloy; the weight percentage of manganese element is 0.3% of the total composition of the alloy; the weight percentage of silicon element is 0.2% of the total composition of the alloy. The composition of the invention is novel, and the production process is reasonable and clear, so that after the alloy melt is solidified into an ingot and extruded into a magnesium-lithium alloy material, while reducing the material density, its overall structure is uniform and fine, and lithium and aluminum elements will The aluminum-lithium phase is precipitated by the reaction, or the magnesium silicide compound is precipitated by the reaction of the magnesium element and the silicon element, so as to improve the rigidity and strength of the magnesium alloy without damaging its ductility.

Description

technical field [0001] The invention belongs to the technical field of metal materials and heat treatment, and relates to a magnesium alloy material and a manufacturing method of the magnesium alloy material. Background technique [0002] With the development of science and technology, the design of various products is now moving towards the goal of light weight and environmental protection. Therefore, a considerable degree of consideration needs to be given to the development of product materials and the selection of characteristics. Among them, the application range of alloy materials is the most extensive. Taking magnesium alloy materials as an example, magnesium metal has the advantages of light weight, high shock resistance, and excellent recyclability among practical metals, and it can be combined with other metal elements. Combined to form a magnesium alloy material with a high strength-to-weight ratio, and good impact and wear resistance. [0003] Taking AZ80 magnes...
