Abstract

The invention belongs to the technical field of metal materials and discloses a high-strength high-toughness magnesium alloy undergoing a controllable reaction with water and a manufacturing method of a component made from the high-strength high-toughness magnesium alloy undergoing the controllable reaction with water. The high-strength high-toughness magnesium alloy comprises, by weight, 8.0%-10.0% of Gd, 2.5%-4.5% of Y, 0.6%-1.0% of Mn, 0.5%-1.0% of Zn, 0.1%-2.1% of mixed reaction acceleration elements (MRAE) including Si, Ni, Ga, In and the like and the balance Mg, and the total weight percentage of impurity elements of Be, Zr and Ca is smaller than 0.01%. Compared with the prior art, the component made from the high-strength high-toughness magnesium alloy has high strength and toughness and can undergo the rapid controllable reaction with water at the indoor temperature or during heating. In this way, the high-strength high-toughness magnesium alloy is suitable for being applied to the industrial fields having the high strength and toughness requirements and the environmental-protection degradation demand for structural materials at the same time.

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 toughness magnesium alloy and a manufacturing method for its components that react controllably with water. 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. [0003] 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 mag...
