Segregation parameters for cells or columnar dendrites of alloys with dry transformation during solidification

An application of the equations governing the microsegregation phenomenon w ith back-diffusion has been presented and referred to the competitive growt h of the delta and gamma phases during peritectic reaction. It allows for i ndependent description of the solute microsegregation and redistribution wi thin both analysed phases. The mode of calculation of both microsegregation and redistribution after back-diffusion has been suggested when non equili brium partition ratio is taken into account. It requires to calculate the d isplacement of the liquidus line and to recalculate the value of non equili brium partition ratio, which should be used in theoretical predictions of p arameters associated with microsegregation and redistribution.
