STRUCTURAL ORDER IN LIQUIDS INDUCED BY INTERFACES WITH CRYSTALS

Abstract

▪ Abstract  Interfaces between solids and liquids are important for a range of materials processes, including soldering and brazing, liquid-phase sintering, crystal growth, and lubrication. There is a wealth of fundamental studies on solid-liquid interfaces in materials, primarily focused on thermodynamics (relative interface energies and segregation effects) from high-temperature wetting experiments, which is often applied to processing design. Less is known about the atomistic structure at solid-liquid interfaces, mainly because of the difficulty involved in obtaining such information experimentally. This work reviews both theoretical and experimental studies of atomistic configurations at solid-liquid interfaces, focusing on the issue of ordering in the liquid adjacent to crystalline solids.
