The flame-resistant magnesium alloy provides a materialogy scheme on the basis of forming a liquid metal layer on the surface for flame resistance of magnesium alloy; furthermore, the alloy is casting magnesium alloy. Through implementation and industrialization of the alloy, the commercial upgrading requirement on the high-quality magnesium alloy material by China in the high-end field can be greatly promoted.

Description

technical field

[0001] The invention relates to the technical field of alloys, in particular to a magnesium alloy. Background technique

[0002] Magnesium is one of the most abundant light metal elements on the earth, with a specific gravity of 1.74g / cm 3 , only 2 / 3 of aluminum, 2 / 5 of titanium, and 1 / 4 of steel. The storage of magnesium in nature is very rich, and it is the third most abundant structural metal in the earth's crust after aluminum and iron. The primary use of metal magnesium is as an alloying element; the second is to manufacture cast and deformed magnesium alloys suitable for structural parts; and finally it is used for desulfurization of steel.

[0003] Magnesium alloys are formed by adding a series of alloying elements to magnesium. According to the manufacturing method, magnesium alloys are divided into cast magnesium alloys and wrought magnesium alloys. Both cast magnesium alloy and deformed magnesium alloy have a series of advantages: (1) In terms o...
