Determination of Fracture Toughness in the Upper Shelf Region Using Small Sample Test Techniques

Popis výsledku v původním jazyce

In this study ultrafine grain structure evolution during high pressure torsion of commercial aluminium alloy AA6082 at increased temperature is presented. Two different initial states of the alloy were prepared by thermal treatment. The progress in structure refinement in dependence on the shear strain level was investigated in thin foils by TEM. The impact of different amount of strain ?ef introduced was analyzed with respect to the effect of increased temperature. The microhardness results measured across the HPT deformed discs pointed out to data scattering. The microstructure analyses results shoved that ultrafine grain (ufg) structure was already formed in deformed disc upon the first turn, regardless the initial structure of alloy, which resultedfrom prior thermal treatment. The heterogeneity in ufg structure development across the deformed discs was observed in thin foils, supporting by received microhardness results scattering. By increasing strain value, applying increasing d
