| Abstract Scope |
Modeling of solidification microstructures requires strong coupling with heat and mass transfers. This is an obvious assertion that is not sufficiently put into force. Instead, simple chaining methodologies are usually preferred. The role of coupling will be demonstrated considering several configurations of a cellular automaton – finite element model. When a large temperature gradient applies, e.g. during welding, the role of Marangoni convection on the transport of heat to determine the melt pool shape will be shown. The role of both heat and solute mass by natural convection on the formation of freckles will also be illustrated upon directional solidification of a turbine blade geometry. Finally, upon equiaxed solidification, recalescence obviously proves the importance of coupling with heat and mass transfers upon the development of the grain structure. |
