Problems solved by technology

[0005] In the Chinese patent ZL00111624.X "Quasicrystal Reinforced Magnesium Matrix Composite Material", Xu Zhou from Shanghai Jiaotong University prepared the AlCuFe quasicrystal reinforced magnesium matrix composite material by stirring casting method, the highest tensile strength is 155.6MPa, and the elongation The highest is 4.1%. It should be said that the magnesium-based composite material prepared by this invention is not enough to meet the demand under the current application conditions; Guo Xuefeng et al. in the Chinese patent (ZL03134363. Quasicrystalline phase reinforced magnesium alloy, and the quasicrystalline content is not easy to control and it is difficult to disperse uniformly, the process is more complicated, the energy consumption is large, it is not a recycled material, and the cost is high

Abstract

The invention discloses a quasicrystal particle reinforced magnesium matrix composite material and a preparation method thereof. The composite material matrix is industrial pure magnesium; the reinforced particle is Mg-Zn-Gd quasicrystal particle, the size of the quasicrystal particle is of 20-100um, and the weight percentage of the quasicrystal particle is of 5-30 percent. The preparation method is as follows: by adopting the repeated plastic deformation technology processing procedure, the proportion of the quasicrystal particles is accurately controlled according to different purposes of the magnesium matrix material, so as to achieve the optimal combination of the intensity and elongation and lead the prepared composite material to meet different needs.

Description

technical field [0001] The invention relates to a magnesium-based composite material reinforced by quasi-crystal particles and a preparation method thereof, in particular to a Mg-Zn-Gd-based thermally stable icosahedral quasi-crystal-reinforced magnesium-based composite material prepared by repeated plastic deformation, which belongs to the composite Materials and light alloy processing field. Background technique [0002] Since the early 1990s, the application and development trend of major metal materials in the world has changed significantly. With the increasing awareness of environmental protection and energy saving, material researchers and product designers pay more and more attention to issues such as product lightweight and recyclability. As the lightest engineering metal material at present, magnesium alloy has become a representative of light metal materials due to its high specific strength and recyclability, and it has continued to grow at a rate of 20% per yea...
