Abstract

Abstract To flake aluminum powder and strengthen the B4Cp/Al composite, pure aluminum powder is natural oxidized and ball milled. The effect of shear deformation on mechanical properties of the forged B4Cp/Al composite with flaked Al are studied. The results show that ball milling can flake the pure aluminum powder, reduce grain size of aluminum, and increase the volume fraction of Al2O3 on the surface of the flaked aluminum. The forging helps to refine the grain size of aluminum. The flow of aluminum matrix is helpful to the uniform distribution of the B4C particles. Shear deformation can refine grain size and also can break the Al2O3 layer, with the increment of strength, hardness, and relative density. After shear deformation, the ultimate tensile strength of the B4Cp/Al composite is 157.0 MPa.
