Embodiment 1
[0034] The rare earth aluminum alloy prepared in this example is composed of the following components by mass percentage: Si: 0.1, Fe: ≤ 0.2, Cu: 0.1, Mn: 1.3, Zn: 4, Cr: 0.5, Ni: 0.25, Ti: 0.22, Zr: 0.7, La: 0.13, Ce: 0.1, Y: 0.05, and the balance is Al.
[0035] (1) Initial melting: Use graphite crucible as a container, raise the temperature until the aluminum matrix is fully melted, add and stir evenly.
[0036] (2) Refining: raise the temperature of the above system to 720°C, and add 0.4wt%C to the 2 / 3 place below the alloy liquid level using a bell jar 2 Cl 6 (Add in equal amounts in 3 times), slowly rotate in the crucible for 20min.
[0037] (4) Rare earth source addition: Keep the above system warm, add Titd-CuLa, Mg-Ce30, Al-Y5 through the bell jar and fully rotate and move for 10min, the rare earth added in the form of Titd-CuLa, Mg-Ce30, Al-Y5 source to avoid the formation of impurities.

Embodiment 2
[0041] The composition and mass percentage of the rare earth aluminum alloy prepared in this example are: Si: 0.15, Fe: 0.5, Cu: 0.05, Mn: 1.2, Zn: 3.5, Zr: 0.05, La: 0.04, Ce: 0.12, Nd : 0.04, Pr: 0.02, and the balance is Al.
[0042] (1) Initial melting: Use graphite crucible as a container, raise the temperature until the aluminum matrix is fully melted, add and stir evenly.
[0043] (2) Refining: raise the temperature of the above system to 710°C, use a bell jar to add 0.6wt% refining agent F to the 2 / 3 place below the alloy liquid level 6 Na 2 Si (add in 5 times in equal amounts), slowly rotate in the crucible for 30min.
[0044] (3) Rare earth source addition: the above system is heated up to 730°C, and the rare earth source praseodymium neodymium mixed metal (25-35% La+40-55% Ce+4-10% Pr+14-18% Nd) is added, And stir well.
[0045] (4) Impurity removal: use a skimming spoon to remove the floating impurities in the above system.
[0046] (6) Forming: transfer the ...
