Abstract

The invention belongs to the technical field of metal materials, and discloses a high-strength and high-hardness magnesium alloy in controllable reaction with water, and a manufacturing method of a component thereof. The magnesium alloy comprises the ingredients in percentage by weight: 9.0 to 15.0 percent of Gd, 3.0 to 5.0 percent of Y, 0.4 to 1.4 percent of Cu, 0.4 to 1.2 percent of Zn, 0.05 to 1.8 percent of the total content of mixed reaction accelerating elements (MRAE) such as Si, Fe, Ni, Ga and In, the balance Mg, and less than 0.01 percent of impurity elements such as Be, Zr and Ca in total. Compared with the prior art, the component manufactured by the magnesium alloy provided by the invention has high strength and high hardness, can be in controllable reaction with the water at room temperature or during heating at the same time, and is suitable to be applied in the industrial field with the requirement on integration of rigorous structure functions such as high strength, high hardness, environmental protection and degradation.

Description

technical field [0001] The invention relates to a magnesium alloy in the technical field of metal materials, in particular to a high-strength and high-hardness magnesium alloy that reacts controllably with water and a manufacturing method for its components. Background technique [0002] Magnesium alloys have the characteristics of low density and high specific strength, and are widely used in various industrial fields. On the other hand, magnesium alloys are chemically more active among existing structural materials, and can be applied in industrial fields that require structural materials to be degradable. Although the chemical properties of magnesium alloys are relatively active, the reaction speed between magnesium and water is extremely weak at room temperature. The main reason is that the magnesium hydroxide produced by the reaction can prevent the further reaction between magnesium and water. to a slower response. Due to the low reaction rate of conventional magnesi...
