||Interfaces in materials can result from phase transformations or also act as initiation sites for phase transformations. Creation or elimination of interfaces in materials impacts the overall system’s free energy, which in turn critically influences the thermodynamics and kinetics of phase transformations. Understanding of evolving interfaces becomes very crucial during thermomechanical processing or while use of materials in various applications involving exposure to external environments such as heat, irradiation or corrosion. With the advancement in high resolution electron microscopy methods, atom probe tomography and X-ray based characterization methods, we are continuously attaining improved understanding of structure, composition and chemical state changes across variety of interfaces in materials and how they change with phase transformations. Improvement in computational methods from atomic scale to mesoscale is also enabling mechanistic analysis of interfaces and phase transformations in materials. Through such new experimental and computational developments, novel insights are being developed about the atomic scale mechanisms of phase transformations as well as how they lead to either formation or elimination of various interfaces in materials.
This symposium invites papers related to the latest developments in experimental and computational studies, focused on how interfaces can trigger phase transformation or how new interfaces are created during phase transformation in materials. We are particularly interested in their interrelationship when the material is subjected to extreme environments of temperature, pressure, mechanical deformation, irradiation, corrosion and coupled environments.
