Abstract Scope |
Recent studies of concentrated solid solutions, which include multi-principal element and high entropy alloys, have underscored the role of varied solute interactions in the driving a wide variety of mesoscale properties. These solute interactions emerge as fluctuations in potential energy that arise from local variations in the chemical environment. In this work, we overview some recent progress in connecting the topological statistics of concentrated solid solutions with the emergent mesoscale plasticity mechanisms. This discussion will begin with a theoretical examination of the fluctuations in defect energies that emerge in concentrated mixtures, followed by a computational investigation of changes in deformation twinning mechanisms in systems with variable defect energies. Extensions of this effort towards quantifying statistics in vacancy formation and migration energies, and other defects associated with high temperature deformation will be overviewed. |
