Fe-Al compound at the interface of steel-mushy Al-20Sn bonding plate was studied quantitatively. The relationship between ratio of Fe-Al compound at interface and bonding parameters (such as preheat temperature of steel plate,solid fraction of Al-20Sn slurry and rolling speed) was established by artificial neural networks perfectly. The results show that when the bonding parameters are 505℃ for preheat temperature of steel plate, 34.3% for solid fraction of AI-20Sn slurry and 10 mm/s for rolling speed, the reasonable ratio of Fe-Al compound corresponding to the largest interfacial shear strength of bonding plate is obtained. Its value is 72%. This reasonable ratio of Fe-Al compound is a quantitative criterion of interracial embrittlement, that is, when the ratio of Fe-Al compound at interface is larger than 72%, interracial embrittlement will occur.
