Abstract

The invention belongs to the technical field of metal materials and discloses a high-plasticity magnesium alloy for a controllable reaction with water and a manufacture method of a magnesium alloy component. The magnesium alloy contains the following ingredients (by weight): 1.8-3.0% of Y, 0-2.4% of Gd, 0-0.8% of Nd, 0.1-0.6% of Mn, 0.05-1.6% of hybrid reaction promoting elements (MRAE) of Si, Ni, Ga, In, etc., the rest of Mg, and impurity elements Be, Zr and Ca being less than 0.01%. In comparison with the prior art, the component manufactured by the use of the magnesium alloy has a certain strength and high plasticity, can conduct a fast controllable reaction with water at room temperature or when being heated, is applicable to the industry sectors which have requirements of high plasticity and degradation on construction materials, replaces rubber or plastic, and meets environmental requirements.

Description

technical field [0001] The invention relates to a magnesium alloy in the technical field of metal materials, in particular to a high-plasticity 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 magnesium alloys and wa...
