Description
Technical Field
The invention relates to the field of metal materials, in particular to a high-strength magnesium alloy capable of rapidly reacting with a medium and a preparation method thereof.
Background
The magnesium alloy is formed by adding other elements into magnesium as a base. The high-strength high-impact-resistance aluminum alloy has the characteristics of small density (about 1.8g/cm3 magnesium alloy), high specific strength, large specific modulus, good heat dissipation, good shock absorption, large impact load bearing capacity compared with aluminum alloy, and good organic matter and alkali corrosion resistance. The method has wide application in various industrial fields, and is mainly used in aviation, aerospace, transportation, chemical engineering, rockets and other industrial departments. The lightest of the practical metals, magnesium has a specific gravity of about 2/3 for aluminum and 1/4 for iron. It is the lightest metal of practical metals, and has high strength and high rigidity. On the other hand, the magnesium alloy is active in chemical properties in the existing material, and can be applied to the industrial field requiring that the structural material has the degradation capability.
Although the magnesium alloy has active chemical properties, the reaction speed of magnesium with water and a water-oil mixture is very weak at normal temperature, and the main reason is that magnesium hydroxide generated by the reaction can prevent the magnesium from further reacting with a medium, and only a slow reaction can be observed even if the magnesium is heated to boiling. Because the reaction rate of the conventional magnesium alloy and a medium is low in a certain temperature range and the controllable range is narrow, the requirement of industrial application cannot be met. The alloying method improves the rate of the chemical reaction between the magnesium alloy and the medium, and simultaneously keeps the high strength of the magnesium alloy, thereby having very important significance for manufacturing structural and functional integrated components.
