Abstract

To flake the pure aluminum powder, ball grinding and forging are used. The mechanical properties of the forged B₄Cp/Al composite are tested. The results show that ball milling can flake the pure aluminum powder. The alumina layer of Al₂O₃ on the surface of aluminum powder are broken during the ball milling and can be dispersed in the matrix as reinforcement. The hardness of the forged aluminum with flaked Al is higher of 19.5% than that without flaked. The forging can increase ultimate tensile strength of the B₄Cp/Al composite. Increasing B₄C volume fraction, the average hardness of the forged B₄C/Al composite with flaked Al powder gradually increases, relative density gradually decreases, ultimate tensile strength first increases and then decreases.
