摘要
Amodelwaspresentedtodescribethemicrostructureevolutionduringthedirectionalsolidificationprocess.Inthismodel,theproblemofdifferentpropertiesinthesolidandliquidphasewassolvedbymakingthepropertiescontinuousatthesolid/liquidinterface.Furthermore,arandomnoisewasincorporatedtoreflecttheanisotropicgrowth.Moreover,theaveragingsoluteconservationwasdevelopedtokeepthetotalsoluteconservationintheinterfaceregion.Asimpleingotwassimulatedbythismethod,themodelcanrepresentthemicrostructureevolution,soluteconcentrationredistribution,micro-segregationandthecolumnar-to-equiaxedtransition.
