摘 要：<正>The bonding of solid steel to liquid aluminum was conducted using rapid solidification.The influence of diffusion time on interfacial shear strength was studied. The results showthat when the temperature of aluminum liquid is 700℃ and the preheat temperature of steel plate is 250℃,the relationship between diffusion time （t） and interfacial shear strength（σ） is σ=15.1+8.14t-037t2 +0.005t3 and the maximum interfacial shear strength is 71.1 MPa.
