摘要：

Most recently, ultrafine-grained and nanostructured aluminum alloys with grain sizes ranging from 100 nm to 500 nm have been successfully manufactured by consolidation of cryomilled aluminum powders. In the present study, uni-axial deformation behavior was used to investigate deformation mechanisms. Microstructure characteristics and X-ray diffraction patterns were also used in the present study. Characteristics of high strength and low work hardening were observed in deformation of cryomilled nanostructured aluminum alloys. The relationship among processing, microstructural characterization and mechanical deformation mechanisms was discussed.
