Problems solved by technology

The current commercial wrought magnesium alloys are mainly Mg-Zn and Mg-Al, but the characteristics of low room temperature strength and difficult plastic deformation limit the further application of magnesium alloys in industry.
Patent 200710078329.X discloses a magnesium-zinc-manganese magnesium alloy with high zinc content, which is cheap, but the tensile strength is lower than ZK60
Patent CN106148785A discloses a deformed magnesium alloy with high ductility at room temperature and its preparation method. The ductility of the magnesium alloy at room temperature has reached 30-50%, but its tensile yield strength is about 110MPa, which is far from meeting the requirements of industrial applications. Therefore, be badly in need of a kind of high-strength high-plasticity magnesium alloy and preparation method thereof

Embodiment 1-3

[0030] Carry out microscopic analysis and performance test to embodiment 1-3 and comparative example preparation magnesium alloy

[0031] 1. Microstructure characterization

[0032] After the surface of the magnesium alloy prepared in Examples 1-3 and Comparative Example was polished flat by No. 400-1200 silicon carbide water-grinding paper, each sample was carried out to phase analysis with an X-ray diffractometer, and the results were as follows: figure 1 shown by figure 1 It can be seen that the diffraction peaks of phase I in the magnesium alloys prepared in Examples 1-3 gradually weaken, indicating that the content of phase I decreases gradually with the increase of Gd content. The diffraction peak of the W phase is gradually enhanced, indicating that the content of the W phase is gradually increasing, and there is no diffraction peak of the W phase in Example 1, indicating that there is no W phase. In the magnesium alloy prepared in the comparative example, the peaks o...

Abstract

The invention relates to a magnesium-zinc-manganese-gadolinium magnesium alloy with high strength and high plasticity as well as a preparation method thereof, and belongs to the technical field of production of magnesium alloys. The magnesium alloy is prepared from the following components in percentage by mass: 5.0 percent to 7.0 percent of Zn, 0.5 percent to 1.5 percent of Mn, 1.0 percent to 8.0percent of Gd, less than or equal to 0.15 percent of inevitable impurities and the balance of magnesium. The magnesium alloy has the advantages of higher strength and higher plasticity; the tensile strength of the magnesium alloy is 316MPa to 373MPa, the yield strength is 234MPa to 333MPa, and an elongation ratio is 11.8 percent to 18 percent. The magnesium alloy is formed through smelting processing and plastic processing; a preparation process is simple, and smelting is carried out by adopting a conventional cast ingot preparation means; and therefore, the magnesium alloy has an industrialuse valve, limitations of a complicated preparation process and harsh preparation conditions of a high-performance magnesium alloy are removed, and the high-performance magnesium alloy can be directlyproduced under existing industrial conditions.

Description

technical field [0001] The invention belongs to the technical field of magnesium alloy production, and in particular relates to a high-strength and high-plasticity magnesium-zinc-manganese-gadolinium-magnesium alloy and a preparation method thereof. Background technique [0002] As the metal structure material with the lowest density at present, magnesium alloy has the advantages of high specific strength, high specific stiffness, good damping performance, and easy cutting and processing. It is widely used in the fields of automobile, electronics, aerospace, and national defense military industry. In particular, the characteristic of low density has broad application prospects in the emerging field of automobile lightweight. It can not only reduce the weight of automobiles, but also reduce energy consumption and emissions, which is of great significance for energy saving and emission reduction. [0003] Magnesium alloys are divided into two categories: wrought magnesium allo...
