Abstract

The invention discloses a magnesium alloy with excellent room-temperature plasticity, and a preparation method thereof, and belongs to the technical field of (metal materials) magnesium alloy. The magnesium alloy is prepared from the following components in percentage by weight: 2-7wt% of Bi, 1.5-4wt% of Y, 0.05-0.15wt% of Mn and the balance of Mg, wherein a Bi / Y ratio is 1.3-2, and Y is more thanor equal to 1.5%. The preparation method for the magnesium alloy mainly comprises the following preparation steps of: smelting, thermal treating and deformation processing. At the room temperature, the alloy has ductility which can be 41% or more, shows excellent room-temperature plasticity, and is a potential magnesium alloy material which can be used for further room-temperature plasticity processing or super-plasticity forming technology processing. Besides, in a casting process and a thermal treatment process, the alloy shows excellent flame resistance.

Description

technical field [0001] The invention relates to the field of metal materials and metal material processing, in particular to a Mg-Bi-Y-Mn high-plastic flame-retardant magnesium alloy and a preparation method thereof; the alloy has excellent plasticity at room temperature and can be used as a low-temperature large plastic deformation magnesium alloy. The blank of the alloy, as well as the potential heat-resistant magnesium alloy material, has broad application prospects and belongs to the technical field of magnesium alloys. Background technique [0002] Energy, materials and information are the three pillars of the development of human society. With the increasingly tight consumption of iron ore and other resources, as well as the increasingly severe situation of energy conservation and emission reduction, the development and utilization of resource-rich magnesium-based materials is an inevitable trend. In metal materials, the density of magnesium is about 1.74g / cm3, which i...
