Solidification processing of metals and alloys has been used for centuries to manufacture complex parts with specific properties and performance. However, a fundamental understanding of solidification – spanning broad ranges in length scale (from atomistic to macroscopic) and timescale (from 10-10 to 104 seconds) for various solidification processes (from conventional casting to additive manufacturing) – is still required. Within this multiscale landscape, the objective of this symposium is to discuss the most recent advances in modeling and experiments, with the goal of mapping and enhancing our knowledge of solidification processes up to the mesoscale.
Broader topics for this symposium, clearly in support of the basic science for advanced manufacturing, include nucleation, phase transformations, transport, and non-equilibrium phenomena. Within these main topics, contributions should focus on, but are not limited to, undercooling/superheating, fluid flow effects, mushy zone dynamics, morphological instabilities, equilibrium and non-equilibrium thermodynamics, micro-segregation, kinetics, and microstructure formation and evolution. Ideally, contributions should couple experimental and modeling results across the scales from pure elements and/or complex multi-component systems, including the effects of processing techniques and parameters on structure-properties relationships.
