Preparation method of high strength, high modulus and high plasticity ceramic particle aluminum-based composite material

[0026] Preparation:

[0027] The ceramic volume fraction of the composite material prepared by the method is controlled at 10-50% vol, and the preparation method is as follows:

[0028] S1 ingredients: According to the volume fraction and gradation theory, mix silicon carbide particles with different particle sizes evenly, and then fill them into the mold. The ratio of silicon carbide particles with a particle size of 200 mesh and a particle size of 800 mesh is 3:1;

[0029] S2 Heating the mold: put the mold into the heating furnace, heat the mold evenly at a rate of 15°C / min, and raise the temperature to 620°C;

[0030] S3 aluminum melting: put the aluminum alloy into the aluminum melting furnace for melting and casting, and vacuumize and stir.

[0031] S4 aluminum injection: move the heated mold to the hot press platform, and inject the aluminum solution in the aluminum melting furnace into the mold.

[0032] S5 hot pressing: adjust the hot press to 1MPa and start pressing
