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 10 mm/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+0.998φ s-0.014 4φ 2 s (where S is interfacial shear strength, φ s is solid fraction). The largest interfacial shear strength is 70.2 MPa when solid fraction is 34.6%. The interface of bonding plate is made up of Fe-Al compound and Fe-Al solid solution alternatively.展开更多
