Method for manufacturing rare earth enhanced type magnalium gadolinium tin alloy plate

Abstract

The invention relates to a method for manufacturing a rare earth enhanced type magnalium gadolinium tin alloy plate. According to the method, in order to overcome the defect that magnesium alloy is low in strength, low in hardness and poor in corrosion resistance, rare earth element gadolinium and non-ferrous metal tin are doped in magnalium, and the rare earth enhanced type magnalium gadolinium tin alloy plate is manufactured through smelting and tableting, solution treatment and hot rolling, wherein the hardness of the rare earth enhanced type magnalium gadolinium tin alloy plate reaches 93 HV, the strength of extension reaches 153 MPa, and corrosion resistance is increased by 95%. The method is advanced in process, the technical parameters are precise, full and accurate, and the method is a very advanced method for manufacturing the rare earth enhanced type magnalium gadolinium tin alloy plate.

Description

technical field [0001] The invention relates to a preparation method of a rare earth reinforced magnesium-aluminum-gadolinium-tin alloy plate, which belongs to the technical field of preparation and application of nonferrous metal materials. Background technique [0002] Magnesium alloy is the lightest non-ferrous metal alloy. It has the advantages of low density, light weight, easy cutting and good processability. It is often used in electronics, automobiles, medical equipment and other industrial fields. However, magnesium alloy has low strength, poor hardness and corrosion resistance. Poor performance and high temperature resistance have greatly limited the application of magnesium alloys. [0003] In order to improve the mechanical properties and heat resistance of magnesium alloys, alloying elements, such as aluminum, zinc, silicon, calcium, manganese, etc., are often added to magnesium alloys. This limits the scope of application of magnesium alloys, such as in aerosp...
