HEms Project

The Hydrogen Embrittlement of Steels (HEMS) project was a consortium funded by the Engineering and Physical Science Research Council to study the damage caused to steels by exposure to hydrogen. Upon exposure to hydrogen steels demonstrate a dramatic decrease in their tensile strength and instead of bending and stretching, the steel "cracks" in a brittle fashion. The HEMS consortium was a collaboration between a number of UK universities to study this phenomenon and elucidate the physical mechanisms underpinning it. If steels could be manufactured which are resistant to this effect it would enable a range of new technologies in the fields of energy and transport, and would be an essential step towards transforming to a hydrogen based energy economy.

DPhil studentship

Currently I have one fully funding DPhil studentship in Materials Modelling, open to UK citizens only due to the nature of the funding. Please contact me to discuss if interested.
