Abstract

A method for preparing a rare earth aluminum alloy powder applicable for additive manufacturing includes: heating and melting aluminum ingots into an aluminum melt; adding required alloy elements to the aluminum melt to obtain an alloy melt in which the alloy elements are present in the following preset percentages by weight: 1.00% to 10.00% of Ce, 0.05% to 8.00% of Mg, 0.10% to 7.50% of Y, 0.10% to 2.50% of Zr, less than 0.1% of impurities, and the balance aluminum; leading out the alloy melt through a fluid guiding pipe, and impacting the alloy melt with a high-pressure gas flow so that the alloy melt is atomized into fine droplets under an action of surface tension, and solidified into spherical alloy powder; and collecting the spherical alloy powder in a vacuum collector, and screening and drying the spherical alloy powder to obtain the rare earth aluminum alloy powder.
