Talk Title: Crystal-Melt Interfaces: Insights from Atomic-Scale Simulations

Series: Lyman L. Handy Colloquium Series

Abstract: The properties of crystal-melt interfaces have long been a topic of substantial interest in materials science, primarily because of their role in governing crystal growth kinetics and morphologies. While the importance of this class of heterophase interfaces has long been recognized, detailed information related to their properties has become available only relatively recently due to advances in both experimental and computational methods. This talk will discuss insights derived over the past decade in the application of atomic-scale computer simulations as a framework for calculating structural, thermodynamic and kinetic properties of crystal-melt interfaces. The talk will include a review of results obtained for elemental metals and model alloy systems with cubic and hexagonal crystal structures, and will illustrate how the detailed information provided by atomistic simulations can be combined with phase-field modeling to derive insights into the origin of complex morphological phenomena in alloy solidification. Recent applications to faceted solid-liquid interfaces, and to rapid solidification in binary alloys with also be discussed.
