| Abstract Scope |
A materials interface is a planar defect that occurs at the intersection of materials with different structural parameters, such as different crystal orientations or phases. The free energy and mobility of interfaces are key parameters in determining microstructural evolution, including grain growth in solids and melting and solidification processes at solid-liquid interfaces. The free energy and mobility of a flat solid-liquid interface have been determined by applying the synthetic driving force (SDF) molecular dynamics method. In this work, we extend the SDF scheme to determine the free energy and mobility of cylindrical grain boundaries and solid-liquid interfaces, in order to investigate the thermodynamics and kinetics of the interfaces in stable and metastable structures. The defect formation process and the rotation of the cylindrical interfaces are also investigated. |
