The recent development of large-scale experimental facilities (both neutron and synchrotron X-ray based techniques) offers unique opportunities to study the deformation and damage process in situ. The aim of this PhD work is to develop and perform transient creep tests as well as detailed creep-fatigue study to unravel the fundamental mechanism for high-temperature deformation and damage process. When these above-mentioned cutting-edge experiments are combined with post-mortem microstructural characterisations, we are in a good position to develop mechanistic-based creep-fatigue models to predict the lifetime of advanced creep-resistant steels. Two candidate materials are considered for this work: one is Type 316LN austenitic stainless steels and the other is P91 type martensitic steels.
This project is partly funded by EPSRC through the SYNERgy programme. 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 microstructural characterisation facilities, high-temperature creep-fatigue 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.
Funding details: This PhD studentship comes with a stipend and fee waiver for 3.5 years. The fee waiver also cover a full overseas fee. The stipend is a standard RCUK rate at which for 2018/9 is £14,777 per year.
In addition, successful applicants should meet the following: • Familiar with mechanics of materials, preferably with a strong capability in designing experimental rigs • Or familiar with the physical metallurgy of materials and have a good knowledge in crystal diffraction • A basic computer programming/coding skill
