Phase-Field Simulations of Rapid Solidification in Binary AlloysFan, Jun 08 1900 (has links)
<p>Rapid solidification is a well established method to produce novel materials with improved
mechanical or electrical properties. The sharp-interface kinetics of rapid solidification
for a binary alloy is summarized. A Phase Field model mapping to this sharp interface
model is summarized and solved by a new adaptive mesh refinement algorithm.
Simulation results are consistent with experiments: The solidification velocity increases
in power-law like fashion at low undercooling and approximately linearly at high undercooling;
The solid/liquid interface undergoes a transition from four-fold dendritic to circular
crystal structures; Solute trapping emerges and the solute partitioning approaches
unity as the solidification velocity increases. Our Phase Field simulations are the first self -consistent
predictions of velocity selection and morphological selection at both low and
high undercoolings and also the first independent check of the solute trapping model in two
dimensions.</p> / Thesis / Master of Applied Science (MASc)

Phase-field modeling of solidification and coarsening effects in dendrite morphology evolution and fragmentationNeumann-Heyme, Hieram 17 September 2018 (has links)
Dendritic solidification has been the subject of continuous research, also because of its high importance in metal production. The challenge of predicting macroscopic material properties due to complex solidification processes is complicated by the multiple physical scales and phenomena involved. Practical modeling approaches are still subject to significant limitations due to remaining gaps in the systematic understanding of dendritic microstructure formation. The present work investigates some of these problems at the microscopic level of interfacial morphology using phase-field simulations. The employed phase-field models are implemented within a finite-element framework, allowing efficient and scalable computations on high-performance computing facilities. Particular emphasis is placed on the evolution and interaction of dendrite sidebranches in the broader context of dendrite fragmentation, varying and dynamical solidification conditions.
