Scope Phase transformations, along with recrystallization, grain growth, and coarsening form the foundational mechanisms governing microstructural evolution during processing (thermo-mechanical or other) of many engineering materials, where the processing is performed to obtain some sort of ideal microstructure exhibiting optimal properties for a specific application. However, many times, engineering materials are designed and processed in such a way that certain phases transformations are expected to occur <I>during</I> service. Phase transformations engineered in this way to produce additional properties beyond those of the static microstructure. Among structural materials the martensitic transformation (both strain and stress induced) could be leveraged to enable the shape memory effect, develop new materials for enhanced tribological properties or even tailor the residual stresses in parts.

This symposium focuses on understanding gaps limiting us from discovering new materials with engineered phase transformations. Specifically, this symposium invites papers related to experimental characterization of engineering phase transformations, investigation of the complex, coupled behavior between multiple external variables, and modeling such behavior. Understanding of such phase transformations includes knowledge of how variables or external fields beyond traditional thermal or thermo-mechanical processing, including internal and external stress fields, electric or magnetic fields, or nuclear radiation, etc. These materials include but not limited to structural materials, shape memory materials, self-healing materials, and magnetocaloric materials.
