preparation example Construction

[0032] The preparation process of the aluminum alloy material comprises the following steps:

[0033]S1: Add aluminum ingots to the electromagnetic induction furnace, increase the temperature to 880-920°C to melt them, add nickel, manganese, copper, and lanthanum powders wrapped in aluminum foil to melt, and stir the alloy melt. After stirring for 15-20min, perform degassing treatment, stand still, and then perform ultrasonic treatment to obtain an aluminum-nickel-manganese-copper-lanthanum alloy intermediate. The temperature of ultrasonic treatment is 800-820°C, and the ultrasonic power is 20-25KW. The processing time is 25-30min; adopt the same method to prepare the aluminum-titanium-zirconium-cerium alloy intermediate; the aluminum-nickel-manganese-copper-lanthanum alloy intermediate and the aluminum-titanium-zirconium-cerium alloy intermediate by weight Making a grain refiner, the size of the grain refiner is below 12 μm;
