Abstract: The bonding of steel plate to aluminum liquid was conducted using rapid solidification.The influence of diffusion time on interfacial structure was studied. The results showed that under the condition of 750ºC for the temperature of aluminum liquid and 200ºC for the preheat temperature of steel plate, when diffusion time was shorter than 4.3 s, there was only Fe-Al solid solution at the interface. When diffusion time was longer than 4.3 s, Fe-Al compound began to form at the interface. The relationships between diffusion time t and thickness of Fe-Al compound layer H are H=-9.72+2.62t-0.08t2 (4.3 s[t[15 s) and H=2.79+0.647t-0.033t2 (t>15 s).
