Abstract: The rolling treatment of steel/mushy Al-20Sn bonding plate was conducted under different relative reduction at room temperature. The effect of room-temperature rolling on interfacial mechanical property of bonding plate was studied. The results show that, for steel/mushy Al-20Sn bonding plate which consists of 1.2mm-thick 08Al steel plate and 2.0mm-thick Al-20Sn layer, the relationship between interfacial shear strength and relative reduction is S=70.1+5.48r-r2(S is interfacial shear strength, r is relative reduction). When the relative reduction is 2.74%, the largest interfacial shear strength 77.6MPa can be obtained.
