Achieving high strength and good laser welding performance by adding Sc to T8-aged Al-Cu-Li alloys with different Cu/Li ratios

Achieving high strength and good laser welding performance by adding Sc to T8-aged Al-Cu-Li alloys with different Cu/Li ratios

In this work, the effects of Sc addition and variations in the Cu/Li ratio on the microstructure, precipitation behavior, laser welding performance, and mechanical properties of Al-Cu-Li alloys were systematically investigated. The results show that the addition of Sc refines as-cast grains, transfo...
