This is a challenging dissimilar joint. However, some investigators obtained successful joints. The automotive company Hyundai successfully applied friction stir welding to join Al-Steel dissimilar couple in engine frame. Intermetallic compounds form during welding which reduce the joint strength and toughness. One can do research on methods to suppress the formation of such compounds. Suitable interlayer materials and the thickness can be optimized.
