Computer Simulation of Phase Separation in Fe-Cr-Mo Ternary Alloys

摘要：

Effect of Mo on phase separation of behavior of Cr in Fe-40at.％Cr-Mo ternary alloys was investigated with use of a model based on the Cahn-Hilliard eqaution. Simulation result indicates that the addition of a small amount of Mo to an Fe-40at.％Cr binary alloy was found to accelerate phase separation of Cr. With addition of small amount of Mo up to 10at.％, the rate of phase separtion concentration of Cr along the trajectory of its peak top increases with time. Mechanism of this acceleration behavior of Cr was analyzed by using a theory on asymptotic behavior of substitutional element in ternary alloy proposed by the present authors.
