Abstract

For advanced aerospace application it is necessary to develop aluminium alloys of new generation with improved service characteristics. For the purpose of increasing mechanical properties of Al–Mg alloys it is purposeful to add small amount of scandium, but small additives of alloying elements with high solubility also can influence microstructure and properties of semi-products. This study deals with effect of small additives of silver, zink and copper in amount not exceeding maximum solubility on microstructure of ingots and cold-rolled sheets of V-1579 type alloy and it’s mechanical properties
