A kind of preparation method of magnesium tin zinc aluminum titanium alloy ingot

Abstract

The invention relates to a preparing method for a magnesium-tin-zinc-aluminum-titanium alloy ingot. The preparing method includes the steps that aimed at the conditions that magnesium and magnesium alloys are low in strength and rigidity and poor in corrosion resistance, magnesium, tin, zinc, aluminum and titanium are mixed, wherein magnesium, tin, zinc, aluminum and titanium all belong to non-ferrous metal; and the magnesium-tin-zinc-aluminum-titanium alloy ingot is prepared through vacuum melting, homogenizing treatment and equal channel angular pressing. The preparing method is advanced in technology, and data are accurate and full; and the product is in a silver long strip shape, the metallographic structure is good in compactness, microhardness is as high as 75 HV to 89 HV, the tensile yield strength is as high as 230 MPa to 275 MPa, the tensile strength is as high as 285 MPa to 365 MPa, elongation is as high as 16% to 21.5%, and the preparing method is a quite-advanced method for preparing the magnesium-tin-zinc-aluminum-titanium alloy ingot.

Description

technical field [0001] The invention relates to a method for preparing a magnesium-tin-zinc-aluminum-titanium alloy ingot, and belongs to the technical field of nonferrous metal alloy preparation and application. Background technique [0002] Magnesium and its alloys have the characteristics of high specific strength, high specific stiffness, and easy processing, and are often used in aviation, aerospace, automobiles, and electronics industries; but most of magnesium and its alloys have low hardness, low strength, and poor corrosion resistance, making them Applications are very limited. [0003] In order to improve the hardness, strength, and corrosion resistance of magnesium and its alloys, magnesium and its alloys are often doped with noble metals or rare earth substances to make them generate reinforcing phases or refine grains, such as CN104099504A patent, using deformation and aging The addition of Pr, Er, and Ho three rare earth elements not only increases the difficu...
