Plastic wrought magnesium alloy and preparation method thereof

The invention provides a method of refining aluminum alloy, which is characterized in that aluminum-based nanometer quasicrystal alloy is used as an aluminum alloy refiner to refine the aluminum alloy; the aluminum-based nanometer quasicrystal alloy does not comprise Si, Fe or Cr; the aluminum-based nanometer quasicrystal alloy consists of (1) Al; (2) Mn and (3) La and/or Ce. The refiner selected in the invention is rare earth-containing alloy which has a strong refinement ability on the aluminum alloy, and is nanometer quasicrystal; after adding the rare earth-containing alloy to melt, the element distribution of the rare earth-containing alloy is more uniform than that of traditional alloy; and nanometer quasicrystal particles substantially increase the number of heterogeneous nucleation particles and improve the grain refinement effect of the aluminum alloy.

Method of refining aluminum alloy

A process of preparing an aluminum alloy includes the following steps: first adding and completely melting a ZL101 Al-Si ingot and then covering the melt next adding one of modifiers Te and Sb and then performing heat preservation; finally adding one or more of rare earth elements La, Ce, Y and transition metal element Hf and then performing heat preservation. The ZL101 Al-Si alloy melt after the treatments can be casted into an ingot or a part after refining.
