Abstract

The present disclosure discloses a Mg-AI based magnesium alloy, and a preparation method of a tube and an application of the same, and belongs to the technical field of alloy materials. The magnesium alloy includes, by weight percentage, 7.0-8.6% Al, 0.8-2.0% RE, 0.2-0.8% Mn, and a balance of Mg, and the magnesium alloy has an elongation of 15-22%. The preparation method of a tube of the Mg-AI based magnesium alloy includes: mixing and smelting an Al source, a RE source, a Mn source, and a Mg source to give a liquid mixed metal; casting the liquid mixed metal into a bar through semi-continuous casting; performing homogenization heat treatment on the bar at 360-400°C for 6-10h; and performing extrusion-forming on the heat-treated bar to obtain a magnesium alloy tube. The Mg-AI based magnesium alloy of the present disclosure has high elongation, and the elongation of the tube formed using the same can reach 15-22%, so that it can withstand large plastic deformation. Meanwhile, the Mg-AI based magnesium alloy has excellent welding performance and a welding loss rate of less than 6%, which greatly reduces the strength loss of magnesium alloy profiles after welding, and ensures the strength of magnesium alloy profiles after welding. The Mg-AI based magnesium alloy can be used in the fields of vehicle equipment and medical equipment.

Abstract

The present invention relates to the technical field of alloy materials. Disclosed are an Mg-Al magnesium alloy, a preparation method for a tube made of the Mg-Al magnesium alloy, and an application of the Mg-Al magnesium alloy. The magnesium alloy comprises, in percentage by weight, 7.0-8.6% of Al, 0.8-2.0% of RE, 0.2-0.8% of Mn, and the balance of Mg, and has an elongation of 15-22%. The preparation method for a tube made of the Mg-Al magnesium alloy comprises: mixing an Al source, an RE source, an Mn source, and an Mg source to smelt into a liquid-state mixed metal; semi-continuously casting the liquid-state mixed metal into a bar; uniformly heating the bar at 360-400°C for 6-10 h; and performing extrusion forming on the heated bar to form the tube made of the Mg-Al magnesium alloy. The Mg-Al magnesium alloy provided by the present invention has a high elongation, and can reach an elongation of 15-22% after being formed into the tube, so as to withstand a large plastic deformation; moreover, the Mg-Al magnesium alloy has excellent welding performance, and has a welding loss rate of lower than 6%, thereby greatly reducing the loss of strength of a magnesium alloy profile after welding, and ensuring the strength of the magnesium alloy profile after welding. The magnesium alloy can be used in the field of vehicle equipment and medical instruments.
