Symposium Deformation-induced Phase Transformations

Scope Mechanical deformation of materials, including deformation applied during processing or in-service, can alter the phase stability or phase transformation kinetics, and subsequently have profound consequences on the mechanical and structural integrity of components. This symposium will explore deformation-driven phase stability, nucleation, separation, and transformation from a fundamental, mechanistic perspective, using both experiments and/or theory. More practical studies that lead to greater understanding of the effect of deformation-induced phase transformation on in-service performance of components, are also of interest.

Topics of interest include, but are not limited to:

* Phase transformations at constant chemical compositions
-Martensitic phase transformations
-Crystal structure change and polymorphism
-Disordering and amorphization
* Phase transformations with chemical composition changes
-Dynamic nucleation
-Precipitation during working, shaping, or forming
* Shape-memory phenomena
* Development of extreme plasticity (e.g. TRIP steels)
* Severe plastic deformation effects
* Effect of phase transformations on mechanical properties or material functionality
* Synergistic computational and experimental studies
