"Ultrafine grain formation during equal channel angular extrusion in an Al-Mg-Si alloy" . "Microstructural development of aluminium alloy 6082 during equal-channel angular pressing was investigated to understand the mechanisms of grain refinement and strain accommodation. The samples were extruded at room temperature. Cross-section of original samples was 8 x 8 mm and their length was 32 mm. Deformation forces were measured during extrusion, resistance to deformation was calculated and deformation speed was determined approximately. Analysis of structure was made with use of light microscopy and SEM. Mechanical properties of samples after extrusion were determined by tensile test and by so called penetration test" .
