My current research focuses on investigating the hydrogen-assisted failure mechanisms of embrittlement in pipeline steels. Various microscopy techniques such as, SEM, AFM, and Scanning Kelvin Probe are used to study the fracture surface of specimens mechanically loaded in air and in hydrogen-rich environments. Neutron and xray scattering measurements help provide structural and dynamic information on these systems by probing deep into the microstructure to quantify localized strain and dislocation densities, in addition to mapping hydrogen kinetics.
