| 摘 要： | Fe-Al compound at the interface of steel-mushy A1-28Pb bonding plate was studied quantitatively. The relationship between ratio of Fe-Al compound at interface and bonding parameters such as preheating temperature of steel plate, solid volume fraction of Al-28Pb slurry and rolling speed, was established by artificial neural networks perfectly. The results show that when the bonding parameters are 546℃ for preheating temperature of steel plate,43.5% for solid volume fraction of Al-28Pb slurry and 8.6 mm/s for rolling speed, the reasonable ratio of Fe-Al compound corresponding to the largest interracial shear strength of bonding plate is obtained as 71.5%. 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 71.5%, interracial embrittlement will occur.

This reasonable ratio of Fe-Al compound is a quantitative criterion of interfacial embrittlement, that is, when the ratio of FeAl compound at interface is larger than 71.5%, interfacial embrittlement will occur. |
