摘要：

A high strength aluminum alloy, with the ratio of 96 wt.%Al-2 wt.%Mg-2 wt.%Cu, has been prepared by mechanical alloying and press-forming. The alloy exhibited a high tensile strength of 780 MPa and a high microhardness of 180 HV. X-ray diffraction characterizations confirmed that the alloy only consists of a solid solution alpha-Al. Microstructure characterizations revealed that the grain size of alpha-Al was about 300 nm-5 mu m. The solid solution strengthening and the grain refinement strengthening were considered to be the reason for such a high strength. (c) 2012 Elsevier B.V. All rights reserved.
