Macroscopic Model for Predicting Columnar to Equiaxed Transitions using Columnar Front Tracking and Average Equiaxed Growth
A macroscopic model of Columnar-to-Equiaxed Transition (CET) formation is presented. The growth of a columnar zone and an equiaxed zone are treated separately and modeled on a fixed grid. The model uses a columnar Front Tracking (FT) formulation to compute the motion of the columnar front and the solidification of the dendritic columnar mushy zone. The model for the equiaxed zone calculates the...
متن کاملEquiaxed dendritic solidification in supercooled melts
The growth of equiaxed dendrites from a pure supercooled melt is examined. We propose modifications to the classical Ivantsov theory that allow for consideration of multiple interacting dendrites. The modified theory reveals the existence of a steady-state dendritic solidification mode in a frame of reference moving with the dendrite tip. This regime should be valid from the onset of nucleation...
متن کاملUsing a Three-phase Mixed Columnar-equiaxed Solidification Model to Study Macrosegregation in Ingot Castings: Perspectives and Limitations
A three-phase model for mixed columnar-equiaxed solidification was recently developed. The most critical features, necessary for modelling the macrosegregation, were considered: the progressive growth of the columnar dendrite trunks from the ingot surface, the nucleation and growth of the equiaxed crystals including the motion of the equiaxed crystals, the thermal and solutal buoyancy flow and ...
متن کاملEquiaxed Dendritic Solidification with Convection Part I. Multiscale/Multiphase Modeling
Equiaxed dendritic solidification in the presence of melt convection and solid-phase transport is investigated in a series of three articles. In part I, a multiphase model is developed to predict composition and structure evolution in an alloy solidifying with an equiaxed morphology. The model accounts for the transport phenomena occurring on the macroscopic (system) scale, as well as the grain...
متن کاملModelling of Equiaxed Grain Growth in Solidification Process
In the last decade problem of dendritic grain structure prediction has been intensively analysed. Several approaches have been proposed including the phase field method, methods related to the Monte Carlo model, cellular automata and finite element methods as well as hybrids of above [13,6,2]. At the same time, to understand a physical background of the process, several experimental studies hav...
