Аннотация
This article presents the results of the work on optimizing the microstructure of a dissimilar laser welded joint of Al-Cu-Li alloys with different Cu/Li ratio. It is shown that welding leads to the formation of an unfavorable microstructure in terms of mechanical properties - dendritic grains of aluminum surrounded by a network of intermetallic compounds. The selected heat treatment (HT) allowed to improve the microstructure of the weld and increase the values of mechanical properties by 36, 25 and 67% for σUTS, σY and δ, respectively.
