The aim of this study was to investigate influence of large plastic strain on microstructure and mechanical properties of aluminium processed by severe plastic deformation (SPD) via equal channel angular pressing (ECAP) method. Polycrystalline high purity aluminium (99,99%) has been deformed at the room temperature by the ECAP in the range 1-12. Pressing velocity was 5 [mm/min]. The microstructure of aluminium was examined using light polarized microscope. To characterize mechanical properties we performed microhardness measurement and tensile tests. Obtained results showed strong interrelation between microstructure and mechanical properties.
