| 摘 要： | 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 0.998ψs-0.0144ψs^2(where S is interfacial shear strength,ψs 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.
