Embodiment Construction

[0017] The high plasticity magnesium alloy described in the present invention will be described in detail below.

[0018] The high-plasticity magnesium alloy of the present invention includes magnesium, zinc, and zirconium in a set mass ratio, and also includes: lithium accounting for 23-27% of the total mass ratio, manganese accounting for 7-9% of the total mass ratio, and manganese accounting for 7-9% of the total mass ratio. The mass ratio is 4-6% of yttrium; and the proportions of the magnesium, zinc and zirconium are respectively 80-83%, 12-15%, and 2-8%.

[0019] Among them, the preferred solution is: the lithium accounts for 25% of the total mass ratio, the manganese accounts for 8% of the total mass ratio, and the yttrium accounts for 5% of the total mass ratio. In addition, the ratios of magnesium, zinc, and zirconium are 80%, 15%, and 5%, respectively.

[0020] The high plasticity magnesium alloy of the present invention can be made according to the following method...

Abstract

The invention discloses a high plasticity magnesium alloy, which comprises the compositions of magnesium, zinc and zirconium in set percentage by mass, and also comprises 23 to27 mass percent of lithium, 7 to 9 mass percent of manganese, and 4 to 6 mass percent of yttrium; and the mass percentages of magnesium, zinc and zirconium are 80 to 83 percent , 12 to 15 percent and 2 to 8 percent respectively. The high plasticity magnesium alloy avoids forming intermetallic compounds by adding such alloying element such as lithium, manganese and yttrium to change the crystal form of magnesium alloy, thereby improving the ductility and the processability of magnesium alloy.

Description

technical field [0001] The invention relates to an alloy, in particular to a high plasticity magnesium alloy. Background technique [0002] The so-called magnesium alloy is an alloy composed of magnesium and other elements. Its characteristics are: low density (about 1.8g / cm3), high specific strength, large elastic modulus, good shock absorption, greater impact load capacity than aluminum alloy, and good corrosion resistance to organic matter and alkali. The main alloying elements are aluminum, zinc, manganese, cerium, thorium and a small amount of zirconium or cadmium. [0003] Magnesium-aluminum alloys are currently the most widely used, followed by magnesium-manganese alloys and magnesium-zinc-zirconium alloys. Mainly used in aviation, aerospace, transportation, chemical industry, rocket and other industrial sectors. According to the forming method, it is divided into two types: wrought magnesium alloy and cast magnesium alloy. [0004] Magnesium alloy is the lightest...
