Abstract
Effect of Mo on phase separation behavior of Cr in Fe-40 at%Cr-Mo ternary alloys was investigated with use of a model based on the Cahn-Hilliurd eqaution. Simulation result indicates that the addition of a small amount of Mo to an Fe-40 at%Cr binary alloy was found to accelerate phase separation. With addition of small amount of Mo up to 5 at%, 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.
