Scope A grand challenge in the production of next-generation transformative materials at scale is to develop manufacturing methods that can circumvent the constraints on chemistry and structure imposed by melt-based processing approaches, and exploit the potential of non-equilibrium synthesis pathways to produce materials with extraordinary performance. Solid Phase Processing (SPP) is one high-potential approach to meeting this grand challenge for metals synthesis and fabrication. In SPP methods (such as friction stir processing/welding, shear assisted processing and extrusion, friction extrusion, cold-spray, ultrasonic consolidation of powders or foil, solid-state additive manufacturing, and in some cases, severe plastic deformation methods such as high pressure torsion, equal channel angular extrusion/pressing and accumulative roll bonding), a high shear strain is introduced into the material, creating a mechanical-thermal coupling that facilitates diffusional processes and phase transformations without requiring the alloy be melted. Because the thermal energy required for material flow is generated entirely by the frictional effects of the process itself, no external heating is required; and the potential exists for rapid heating and cooling, combined with kinetically-driven atomic movement, to enable controlled production of metastable phases. However, a fundamental understanding of the deformation physics, how they affect microstructural evolution, and in turn, how these influence the mechanical/functional behavior, are lacking. Such understanding is critical to harness the potential of SPP methods for unprecedented materials performance.

This symposium is intended to cover a broad scope of solid phase processing fundamental studies up to potential applications. It will provide a forum to discuss fundamental physics and deformation mechanisms during SPP and microstructural evolution under SPP conditions. Abstracts are solicited that cover emerging processing approaches, characterization and theory/modeling of SPP methods and novel experimental approaches that reveal the deformation physics, analysis of defects, and their role of the resulting microstructural evolution and properties. Topics of interest include, but are not limited to:

•Novel process condition probing methods for microstructural evolution correlation
•Advanced characterization techniques (e.g. in-situ electron microscopy, light source studies, nano/micromechanical testing, tribological approaches, etc.)
•Micro-, meso- and nanoscale theory and modeling of deformation (e.g. ab-initio, MD simulations, phase field simulations, etc.)
•Explorations of the deformation or rapid thermal processing conditions promoting persistent metastable phases
•Characterization of SPP material performance in extreme environments (mechanical, irradiation, corrosion, etc.)

To avoid overlap with traditional friction stir welding/processing, preference will be given to papers highlighting fundamental insights, novel in-situ studies, broadly applicable computational tools in emerging SPP platforms, technologies and advancements.
