Mechanism of the Interfacial Reaction of AI_2O_3/Medium Mn Steel Containing Nb

Abstract

Abstract: The mechanism of the interfacial reaction of Al_2O_3/medium Mn steel containing Nb was studied by means of the observation on the interfacial reaction phenomenon of Al_2O_3/medium Mn steel,and the analyses on the interracial phases.The results show that when T≥1550℃,the interfacial reac- tion of Al_2O_3/medium Mn steel containing Nb happened.In the medium Mn steel matrix,Nb exists in the form of NbC.NbC are the nucleating base of CO gas bubbles.

Key words: Nb, medium Mn steel, Al_2O_3, interfacial reaction
