One of the main drawbacks of welding dissimilar metal alloys is the potential massive precipitation of deleterious intermetallic compounds that occurs at the interface joint. Solid-state welding processes are therefore attractive, given the lower temperatures involved. In this work, dissimilar high strength aluminum and titanium alloys were friction-stir-welded using the spindle power control mode to reduce the heat input at the joint as much as possible. A microstructural characterization indicated that the chosen parameters (heat input of ~0.5 kJ/mm) produced welded joints without spatially continuous layers of deleterious intermetallic compounds
