An analytical microsegregation model quantifies the effects of solid-state diffusion between the cases of Scheil and Lever rule, and it has been widely applied to predict microsegregation characteristics. For multicomponent steels, the liquidus correlation can be introduced in the analytical microsegregation model to determine the effects of all the individual components, followed by an investigation of the relationship between temperature and solid fraction. However, investigations on the analytical microsegregation model show that there is an inconsistency in the solidus temperature, and therefore, a certain solidus temperature value is required as input for calculating the solidus temperature value using the model. In our previous work, we investigated this inconsistency, and the results suggested that the input solidus has only a slight influence on the predicted results. In the present study, we investigate the influence of input solidus on the output throughout the solution procedure of single-phase solidification. Herein, based on low (0.04C, δ-solidification) and high carbon (0.55C, γ-solidification) steel, the inconsistency in the solidus temperature is clearly analyzed, and the results confirm that the deviations in the solidus temperature can be ignored. We believe that providing a reasonable solidus temperature value as an input while solving the analytical microsegregation model is feasible and reliable. |
