Developing hydrogen-tolerant steels
Hydrogen atoms and gas can penetrate into steels - and be located in various positions within the steel structure
Hydrogen atoms and gas can penetrate into steels, and interact with the structures within the steel. This often causes internal stress and strains, which embrittle the steel. Such hydrogen embrittlement reduces the working life of the steel. Developing an understanding of the underlying microstructural defects and elemental segregation for trapping hydrogen, we propose to develop mechanisms to mitigate hydrogen embrittlement. And, use these mechanisms as the basis for designing hydrogen-tolerant steels. That is, steels that have a longer lifetime when in service in hydrogen environments.
