Friction stir welding (FSW) of dissimilar joints offers serveral advantages over conventional fusion joining techniques since no associated melting is involved. In this study, FSW was applied to join AA6181‐T4 aluminium alloy to HC340LA high strength steel and a systematic investigation of the microstructure formation, the development of Fe x Al y intermetallic compounds and their influences on the mechanical behaviour is presented. Based on fractography analyses, a possible failure scenario for the joint during shear test is also proposed.
