Sažetak
Prikazani su rezultati uticaja mikrostrukture na korozijsko-mehaničku izdržljivost legure sistema Al-Mg-Si-Cu debljine 1,2 mm i njenih zavarenih spojeva čije stanje određuje vrsta termičke obrade. Promena mikrostrukture zavarenih spojeva usled različitih postupaka termičke obrade praktično ne utiče na otpornost na piling koroziju i intergranularnu koroziju. Ne može se sa sigurnošću odrediti uticaj termičke obrade na korozijsko-mehaničku izdržljivost zavarenih spojeva u uslovima istovremenog dejstva kontinualnog opterećenja i korozijskog okruženja. Otpornost na intergranularnu koroziju i koroziono razaranje odrediće otpornost na prelom zavarenih proizvoda od legure V1341T.
