摘要
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 7graphite slurry, the relationship between interfacial shear strength S and diffusion time t is S =25.3+4.47 t- 0.133t 2 +0.001t 3 . When diffusion time is 22.5 s, the largest interfacial shear strength 69.9 MPa is got, and the corresponding interface is made up of Fe Al compound and Fe Al solid solution alternatively and in a right proportion.
