Overview
We study friction extrusion, friction stir processing, additive friction stir deposition, and related severe-plastic-deformation routes to connect processing path with microstructure and performance.
Research questions
How do local thermomechanical histories control grain refinement and texture?
How can solid-phase routes consolidate powders and manufacture complex forms?
