Abstract
Abstract To flake aluminum powder and strengthen the B 4 Cp/Al composite, pure aluminum powder is natural oxidized and ball milled. The effect of shear deformation on mechanical properties of the forged B 4 Cp/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 Al 2 O 3 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 B 4 C particles. Shear deformation can refine grain size and also can break the Al 2 O 3 layer, with the increment of strength, hardness, and relative density. After shear deformation, the ultimate tensile strength of the B 4 Cp/Al composite is 157.0 MPa.
期刊介绍：
Materials Testing is a SCI-listed English language journal dealing with all aspects of material and component testing with a special focus on transfer between laboratory research into industrial application. The journal provides first-hand information on non-destructive, destructive, optical, physical and chemical test procedures. It contains exclusive articles which are peer-reviewed applying respectively high international quality criterions.
