Abstract: The slurry of Al-20Sn alloy was prepared using electromagnetic-mechanical stirring method. The bonding of steel/mushy Al-20Sn was conducted using casting rolling technique. The bonding parameters were 505℃ for preheat temperature of steel plate and 10mm/s for rolling speed. The interfacial mechanical property and structure of steel/mushy Al-20Sn bonding plate were studied. The results show that the relationship between solid fraction of Al-20Sn slurry and interfacial shear strength of bonding plate is S=52.9+0.998φs-0.0144φs2 (where S is interfacial shear strength, φs is solid fraction). The largest interfacial shear strength is 70.2MPa when solid fraction is 34.6%. The interface of bonding plate is made up of Fe-Al compound and Fe-Al solid solution alternatively.
