Surface segregation kinetics in binary alloys

摘要: Abstract An integral equation describing the kinetics of surface segregation in a binary alloys is derived. Solution this yields well-known McLean form for when enrichment ratio independent segregant concentration. In other cases nonlinear and must be solved by numerical techniques general. However, here, an alternative approximate analytical scheme developed which entails only solution sequence linear equations. This method used to expose qualitative features effect concentration-dependent upon kinetics. The practical utility approach also established analysis real system. results given agree with those found prior workers using methods.
