| Abstract Scope |
For decades, severe plastic deformation approaches such as high pressure torsion and equal channel angular extrusion have probed the limits of novel defect and microstructure evolution under pressure-confined shear deformation. However, deformation under similar conditions has been occurring for eons in the geological materials in earth's lithosphere. Cross-cutting theories on the nature of intense pressure and shear-driven structural evolution in metals and geological materials will be presented, along with novel characterization methods used to understand defect evolution for the corresponding conditions and time-scales. The discussion will forecast the ability to use laboratory-scale tools and simulant materials to extend our understanding of how the world has moved underneath us and how it may deform in other parts of the universe. |
