Embodiment

[0011] The materials are AM60 magnesium alloy ingot and pure metal Bi. The AM60 magnesium alloy was melted in a crucible resistance furnace. In order to prevent the oxidation and combustion of the magnesium alloy, a covering agent was used to protect the melt. When the temperature reaches 720°C, keep warm, and add pure metal Bi with mass fractions of 0.8%, 1.0%, and 1.2%, respectively. In order to fully dissolve Bi and make the composition uniform, the melt is kept warm for 15 minutes. Then, pour the melt into a steel mold to make an ingot of d30mm×120mm.

[0012] Table 1 shows the effect of Bi content on the mechanical properties of AM60 magnesium alloy. It can be seen that with the increase of Bi content, the tensile strength, hardness and plasticity of AM60 magnesium alloy are all improved. The tensile strength, hardness and elongation of AM60 magnesium alloy without Bi are 176.3MPa, 54.5HBS, 7.38%. When the Bi addition is 1.0%, the tensile strength, hardness and elongati...

Abstract

The invention discloses a method for improving the performance of AM60 magnesium alloy by adding the alloy element Bi into the AM60 magnesium alloy. The method for improving the performance of the AM60 magnesium alloy by adding the alloy element Bi into the AM60 magnesium alloy comprises the steps that the AM60 magnesium alloy is placed into a crucible resistance furnace to be smelted; a covering agent is used for protecting melt so as to prevent oxidative combustion of the magnesium alloy; when the temperature reaches 720 DEG C, heat preservation is conducted, and the pure metal Bi is added; and heat preservation is conducted on the melt for 15 min so that the Bi can be fully dissolved and the elements can be uniform, and then pouring is conducted. By the adoption of the method for improving the performance of the AM60 magnesium alloy by adding the alloy element Bi into the AM60 magnesium alloy, the performance of the alloy is improved, and the production cost is reduced.
