Nano- and Micro-mechanical testing of fusion steel: the effect of temperature and strain rate
In the absence of a comprehensive database of materials properties for the in-vessel components of a spherical tokamak for fusion energy production, predictive models and advance simulation techniques will be required.
UKAEA is currently developing predictive models that are based on a mechanistic understanding of microstructure-mediated deformation and failure. The robust data of properties (dislocation slip, hardening law and microstructural evolution parameters) of individual constituents under as closest to fusion condition as possible are required.
Instrumented indentation and related micro-mechanical testing are used for the measurement of highly spatially resolved mechanical response of materials. The project will contribute essential understanding and measurement of plasticity of iron based fusion alloys, including temperature, strain rate and irradiation effects via instrumented indentation, to qualify the crystal plasticity model performance.
Applicants should have, or expect to achieve, at least a 2.1 Honours degree or a Master’s (or international equivalent) in a relevant science or engineering related discipline. This project will be delivered in collaboration with the National Physical Laboratory (NPL), the UK’s National Measurement Institute.
The successful candidate will be supported and trained by experts at NPL and will have access to facilities and equipment relevant to the project. They will also gain access to professional development opportunities, training and support offered through the Postgraduate Institute for Measurement Science (PGI). We strongly recommend that you contact the supervisors for this project before you apply.
