The key degradation mechanisms for the high-temperature nuclear reactors is the creep fatigue of steel components. When structural materials (e.g. Type 316LN stainless steels) are used at high temperature, thermal ageing and inelastic deformation lead to changes in their microstructures . The creep and creep-fatigue performance of structural materials are limited by the degradation of microstructures. The underlying need is to develop improved understanding and predictive models of the evolution of the key microstructural features which control long-term creep performance and creep-fatigue interaction.
The aim of this PhD work is to use advanced materials characterisation techniques covering different length-scales to understand microstructural degradation as a result of high-temperature service for creep-resistant steels.
This project is partly funded by EPSRC through the SYNERgy programme (https://gow.epsrc.ukri.org/NGBOViewGrant.aspx?GrantRef=EP/R043973/1). You will need to engage with all the project partners that particularly include Universities of Oxford and Manchester. The PhD candidates will have full access to all high-end microstructure characterisation facilities, mechanical testing facilities, and the UK’s word-leading neutron and synchrotron X-ray large-scale facilities. This project also comes with financial supports for attending international meetings/workshops.
