We study stress corrosion cracking, hydrogen embrittlement, and corrosion fatigue of metallic materials. Our predominantly experimental approach aims to understand damage mechanisms by combining expertise in physical metallurgy, mechanics, and electrochemistry.
Research Areas
- Hydrogen-microstructure interactions, diffusion/segregation,
- Crack/microstructure interaction
- Microstructure design
Resources
- Mechanical testing in controlled electrochemical environments, micromechanics,
- Characterization by SEM, TEM, EBSD, AFM/SKPFM, Auger/XPS, X-ray diffraction and tomography, electrochemical hydrogen permeation, thermal desorption,
- Finite element modeling.
