摘要

The subject of the research was an alloy AlZnMg and AlCuMg with addition of Zr and Ag manufactured of powders by hot plastic consolidation in process of direct extrusion. Paper also presents results of research of structure evolution and mechanical properties for different tempers of precipitation strengthening and further plastic deformation, including hydrostatic extrusion. Obtained results R_m above 700MPa (for AlZnMg alloy) and above 500MPa (for AlCuMg alloy) shows significant possibilities of manufacturing from Al alloys powders products with ultrafme grain and nanometric structure which properties exceeding alloys manufactured with standard methods.
