Modeling and Simulation of Microstructure Evolution in Solidifying Alloys

The aim of Modeling and Simulation of Microstructure Evolution in Solidifying Alloys is to describe in a clear mathematical language the physics of the solidification structure evolution of cast alloys. The concepts and methodologies presented here for the net-shaped casting and the ingot remelt processes can be applied, with some modifications, to model other solidification processes such as welding and deposition processes. Modeling and simulation of solidification structure evolution requires complex multi-scale computational techniques, from computational fluid dynamics macroscopic modeling, through mesoscopic to microscopic modeling, as well as strategies to link various length-scales that emerge in modeling of microstructural evolution. Another aim of the book is to provide simulation examples of the solidification structure modeling in some crucial commercial casting technologies as well as to provide practical techniques for controlling the structure formation during the solidification processes. The simulation codes (PC versions) for 2D (includes fluid flow computations) and 3D mesoscale dendrite growth models (for 2D and 3D simple casting geometries) written in Visual For
