详细
Aluminum composites doped with copper (4 wt %) with micro-additions (0.01–0.15 vol %) of oxide nanoparticles (Al2O3, ZrO2, MgO, SiO2) are synthesized by the powder metallurgy method. Their microstructure and mechanical properties (Brinell hardness number, Vickers microhardness) are investigated. Existence of phases CuAl2 both on the boundaries and inside grains of the matrix are revealed. Optimal concentrations of nanoparticles that provide high mechanical properties are determined. For Al–Cu material with 0.15 vol % of aluminum oxide, a maximum increase in Brinell hardness of 17% (68 HB) with respect to aluminum composite without nano-additions sintered according to the same technology is observed. Among the investigated materials, the highest Vickers microhardness of 0.543 GPA is intrinsic to aluminum composite with Al2O3 content of 0.1 vol %.
