dc.description.abstractIn this work, the structural and mechanical properties of friction stir welded dissimilar butt joints of AA2024-T351 to AA5083-H112 aluminum alloys were evaluated. Plates of 6 mm thick were friction stir welded with optimized tool. In the first case, plate of AA2024 was positioned on the advancing and plate of AA5083 was on the retreating side of the weld. In second case, position of the plate was opposite. Specimens were welded using rotation rate of 750 rpm and welding speed of 73 and 93 mm/min. Specimens were defect free, with good or acceptable weld surface. The effects of rotation and lateral speed of the welding tool were related to structural features and mechanical properties. The structural appearances of concentric rings in the nugget zone were controlled by tool speed and plate position. Structural analysis of the joint cross-section, revealed the distinct lamellar bands. The joints consistently failed on the AA5083 aluminum alloy plate. Failures were observed through the heat-affected zone at distance of approximately 21 mm from weld center.en
dc.description.abstractU radu su predstavljeni rezultati strukturnih i mehaničkih ispitivanja sučeonih spojeva raznorodnih aluminijumskih legura AlCu4,5Mg (AA2024) i AlMg4,5Mn (AA5083) zavarenih postupkom FSW. Primenom optimizovang alata za zavarivanje, spojene su ploče debljine 6 mm. Međusobni položaj ploča u spoju je variran tako da je u prvom slučaju ploča od AA2024 pozicionirana na strani napredovanja a ploča od AA5083 na povratnoj strani spoja. U drugom slučaju položaj ploča je bio obrnut. Korišćeni su sledeći parametri zavarivanja: brzina rotacije alata nije menjana i iznosila je 750 obr/min a brzina zavarivanja iznosila je 73 i 93 mm/min. Dobijeni su spojevi bez prisustva grešaka i sa glatkom odnosno prihvatljivo ravnom površinom spoja. Analiziran je uticaj parametra zavarivanja na dobijenu strukturu i mehanička svojstva spoja. Oblik grumena i u njemu prisutnih koncentričnih krugova, zavisi od brzine zavarivanja i položaja ploča u spoju. Do loma uvek dolazi na strani spoja gde je pozicionirana ploča od legure AA5083. Karakteristično je da se lom uvek dešava na rastojanju od oko 21 mm od centra spoja.sr
