Project Description:
Zero carbon energy systems are needed urgently and hydrogen has been identified by the UK government as having a key role in future energy systems. However hydrogen is well known to have a deleterious effect on the mechanical properties of many metallic systems. These can include magnesium alloys for hydrogen storage, platinum and palladium in fuel cells, or pearlitic steels in hydrogen transmission. In all cases the effect that hydrogen has on basic mechanical properties is not well understood and an improved understanding will accelerate the development of a hydrogen-based energy economy. Using a new in-situ electrochemical nanoindentation cell this project will compare the mechanical behaviour of industrially important metals with and without hydrogen charging. By working with nanomechanical testing methods we will be able to correlate the effect of hydrogen on the local microstructural environment around the mechanical test. Combinations of exsitu and in-situ nano-mechanical testing, will be used along with SEM, HR-EBSD, and AFM characterisation.
