Abstract: The bonding of steel plate to Al-7graphite slurry was conducted using casting rolling technique. The influence of diffusion time on interfacial mechanical property and structure of bonding plate was studied. The results show that: under the condition of 510℃ for preheat temperature of steel plate and 32% of solid fraction of Al-7 graphite slurry, the relationship between interfacial shear strength S and diffusion time t is S=25.3+4.47t-0.133t2+0.001t3. When diffusion time is 22.5s, the largest interfacial shear strength 69.9MPa is got, and the corresponding interface is made up of Fe-Al compound and Fe-Al solid solution alternatively and in a right proportion.
