It was well established that the grain size of metallic alloys may be substantially refined with a severe plastic deformation (SPD). The present work focuses on equal-channel angular pressing (ECAP) as the most used method of SPD for grain refinement inducing a significant enhancement to the mechanical and functional properties of the commercial AA5754. ECAP with up to 6 passes resulted in a substantial grain-size reduction from 70 %m of an as-received sample to 5 %m. The aforementioned reduction of the grain size increased the microhardness by a factor of 4. These results were compared to those of AA3004"},{"@xml:lang":"sl","#text":"Zadnjih nekaj let vzbujajo pozornost znanstvenikov in tehnologov mehanske lastnosti materiala z ultradrobnimi zrni (UFG). Ugotovljeno je bilo, da je z uporabo velike plastične deformacije (SPD) mogoče močno zmanjšati velikost zrn v kovinski zlitini. To delo poroča o metodi \"equal-channel angular pressing\" (ECAP) kot najpogosteje uporabljeni SPD za zmanjšanje zrn, ki povzroči občutno povečanje mehanskih in funkcionalnih lastnosti komercialne zlitine AA5754. ECAP povzroči občutno zmanjšanje velikosti zrn iz 70 %m pri dobavljeni zlitini na 5 %m po 6 prehodih. Omenjeno zmanjšanje velikosti zrn je povečalo mikrotrdoto za faktor 4.
