Özet

In this study, simple analytical microsegregation models for constant cooling and parabolic growth are proposed considering dendrite arm coarsening effect with and without back diffusion. These simple models are compared with the Mortensen exact model and Voller's models. It is shown that these analytical models can be used to predict approximately microsegregation in a binary alloy.
