The key degradation mechanisms for the high-temperature power plant system is the microstructural degradation and creep-fatigue of steel components. When structural materials (e.g. Type 316L 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 and deformation kinetics so that their high-temperature mechanical performance can be predicted.
The aim of this PhD work is to use a range of advanced microstructure and mechanical testing tools covering different length-scales to fully characterise the evolution of both the microstructure and mechanical properties on advanced austenitic stainless steels due to high-temperature exposure with and without loading. The candidate materials will be fabricated with powder-bed additive manufacturing techniques.
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.
Applicants are required to hold/or expect to obtain at least a UK Bachelor Degree 2:1 or better, or overseas equivalent in materials, mechanical engineering or relevant subject area.
