Abstract

Si₃N_4p/2024Al composite was fabricated by squeeze casting method and treated by extrusion deformation. Microstructure analyses indicate that Si₃N₄ particles in the composite are in cylindrical polyhedron shape. Extrusion deformation is beneficial to uniform distribution of Si₃N₄ particles and improves the relative density of Si₃N_4p/2024Al composite. Tensile strength of Si₃N_4p/2024Al composite increases by 76.6 after T6 treatment, and after extrusion and T6 treatment it is by 57.6 more than T6 treatment only. Elastic modulus of Si₃N_4p/2024Al composite increases a little after T6 treatment but increases by 33.5 after extrusion deformation.
