AbstractAl-free ZK60 magnesium (Mg) alloy sheet was selected as substrate material of Mg-steel pinless friction stir spot welding (FSSW), avoiding the effect of the Al element in the substrate on the alloying reaction of Mg-iron (Fe) interface. The sound FSSW joint of ZK60 Mg alloy and Q235 steel with a hot-dipped aluminum (Al)-containing zinc (Zn) coating was successfully realized. The detailed microstructural examinations proved that Al5Fe2 phase at the Mg-Fe interface came from the pre-existing Al5Fe2 phase in the coating and acted as the transition layer for promoting the metallurgical bonding of Mg and Fe. The interfaces with well-matched lattice sites among Fe, Al5Fe2 and Mg were formed during FSSW. A low energy interface with good match of lattice sites ((002)(Al5Fe2)//(110)(Fe), [110](Al5Fe2)//[(1) over bar 13](Fe)) between Al5Fe2 and Fe was identified. For the interface between Al(5)Fe(2)and Mg, an orientation relationship of (6 (2) over bar2)(Al5Fe2)//(3 (112) over bar)(Mg) and[1 (58) over bar](Al5Fe2)//[2 (4) over bar 23] (Mg) was observed. The tensile-shear load of the ZK60-steel joint could reach 4.6 kN. Moreover, the joint fracture occurred at the interface between the Al5Fe2 layer and the Mg alloy substrate, suggesting the brittle fracture characteristic.
