Ultrafine grain and nanocrystalline materials show attractive properties - very high strength and relatively good ductility. Such metals can be produced by severe plastic deformation methods. In the previous work , it was shown that the hydrostatic extrusion results in grain refinement to nanometer scale of aluminium alloys. This processing method can be used to produce large fully-dense bulk elements (rods of various cross-section shapes and lengths much higher than in other techniques). The aim of this work was to show how the properties of nano-sized age hardenable aluminium alloy depend on the initial microstructure (single or two-phase) of extruded samples.
