Embodiment 1
[0020] The chemical composition of the new magnesium alloy composite material is aluminum: 12.0%, zinc: 2.1%, manganese: 1.2%, neodymium: 0.5%, cerium: 0.5%, and the balance is magnesium. Nickel-coated nano-SiC particles with a diameter of 55 nm were added to the molten magnesium alloy material, the addition amount was 4.0 wt. %, the magnetic induction intensity of the electromagnetic field was 0.6 T, and the excitation current was 40 A. After casting, an electric field is applied to the ingot to refine the grains, the pouring temperature is 840 ℃, and the current density of the electric field is 1600 A / cm 2 , the frequency is 1200 Hz, and the pulse width is 45 μs. Then, the new magnesium alloy composite material is deformed by equal-path angular extrusion, and the inner angle of the equal-path angular extrusion die is Φ=120°.
