Ultrafine structure formation in aluminium alloy processed by HPT and the mechanical properties response

Original language description

In this study ultrafine grain (ufg) structure evolution during high pressure torsion (HPT) of commercial aluminium alloy AA6082 at increased temperature is presented. The progress in structure refinement in dependence on the shear strain level strain wasinvestigated by TEM of thin foils. The impact of different amount of strain (?ef) introduced was analyzed with respect to the effect of increased temperature. The results of microstructure analyses showed that ultrafine grain structure was already formed in deformed disc upon the first turn, regardless the initial structure of alloy, resulting from prior thermal treatment. The heterogeneity in ufg structure formation across the deformed disc was observed, supporting microhardness scattering results. Byincreasing the strain level (number of turns N -2,4,6), more effectively homogenized ufg structure was observed across the deformed discs. The effect of increased deformation temperature became evident and dynamic recrystalization modifi
