Braze Alloy Development for Advanced Repair of Aeroengine Components
Brazing offers the prospect of revitalising high temperature structural components in the gas turbine engines used for civil aviation, thereby extending service life and reducing cost. For the reliable deployment of this technology, the microstructural and property changes that occur as a result of the process must be fully understood. This is particularly important for the highest performance alloys used in large civil engines, which encounter demanding service conditions.
PhD Project Overview
This PhD project will seek to carry out the fundamental metallurgical research required to understand how elemental redistribution takes place between the constituents of repair brazes in superalloys. This will involve detailed characterisation using scanning and transmission electron microscopy, X-ray diffraction, and mechanical testing. Thermodynamic and kinetic modelling will also be performed to build a predictive capability of how interdiffusion proceeds during processing and the nature of the phases that are formed. The insights obtained will be used to optimise braze alloy chemistry and processing as well as better understand the impact on braze repair on the adherence of protective surface coatings. The PhD will be conducted in close collaboration with Rolls‑Royce plc.
Qualifications
Applicants should have (or expect to be awarded) a good UK Master’s degree (or overseas equivalent) in a relevant science subject (Materials Science, Chemistry, Physics, Engineering) and should be self‑motivated, able to take ownership of their research, and effectively communicate their research findings. Training in all the computational and experimental methods will be provided in the project, although relevant previous experience would be advantageous.
