Symposium description
In a broad range of materials, it is the micro- or nanoscale structure that dictates a material’s macroscopic behavior and its engineering properties. The material structure is in many cases defined by different phases, regions or constituents, separated by interfaces. Within the scope of this session, the term “interfaces” may be interpreted quite generally to include grain boundaries, cracks, and phase boundaries. In addition, phases and interfaces will tend to evolve in time, for example, as the material is exposed to deformation, temperature changes or other stimuli, such as electrical currents. Furthermore, interfaces are strongly related to microstructure degradation processes, such as electromigration in conducting wires and creep deformation in metals at elevated temperatures. It is also recognized that interfaces can be engineered features of a given specimen, introduced, for example, by grain boundary engineering or by additive manufacturing in the context of multi-materials. Included within the scope of the session are solid-state transformations, such as recrystallization, grain growth, phase transformations occurring by diffusion-based mechanisms or without diffusion, e.g., martensitic transformations, as well as solid-state precipitation.
A particular focus of the session is numerical modeling of the creation, evolution and disappearance of interfaces as well as of solid-state transformations in different physical settings. Interface mechanics and solid-state transformations are of importance for a wide range of materials, and session contributions may be related to interfaces and/or solid-state transformations in metals, ceramics or geomaterials.
The session covers, but is not limited to, the following topics:
Links between materials processing and solid-state transformations and interface evolution
