Research briefing:

My PhD research project is <Exploring the Grain Refinement Mechanisms Induced by High-Pressure Torsion Processing>. Currently, I am working on three projects: (1) Tribology study of Al-Si composites; (2) Tribology study of nano-twinned copper; and (3) Constitutive behavior of steels under high strain rates. I implement various materials characterization techniques to study the evolutions of microstructures and mechanical properties of metallic materials/composites during plastic deformation processes.
