A new liquid-phase bonding method was developed to establish a strong bonding between Al bearing Mg alloys and steels by intentionally forming a thin and uniform reaction layer at the bonding interface. By adopting Ag as an interlayer between the Mg alloys and steel, Mg-Ag eutectic melt is produced at 773 K and nano-scale Fe-Al reaction layer is uniformly formed at the melt-steel interface during the isothermal solidification of the melt which is driven by the diffusion of Ag into the Mg alloy. At the completion of the solidification, exceptionally strong bonding, exceeding the yield strength of the base Mg alloys, is achieved.
