Overview
We seek to appoint a researcher who will be responsible for cavitation erosion and fatigue testing of newly developed aluminium alloys for Additive Manufacturing processes. The position is for a Postdoctoral Research Assistant in the project "Performance-driven design of Aluminium alloys for high-accuracy Additive Manufacturing" (PAAM) in the department of Engineering, Computing and Mathematics (ECM) at Oxford Brookes University, Oxford, U.K. The role is 12-month fixed-term and funded by the Engineering and Physical Sciences Research Council (EPSRC).
Responsibilities
* Lead cavitation erosion and fatigue testing of as-cast and AM test parts.
* Take acoustic pressure measurements and perform in-situ high-speed imaging to study failure mechanisms.
* Conduct microstructural characterisation and analyse results to support the project goals.
* Collaborate with Brunel University of London, University College London (UCL) and industry partners; participate in data acquisition, processing and interpretation.
* Support the testing, characterisation and critical evaluation of prototype AM test pieces.
* Handle and process large data sets; apply signal and image processing techniques; manage data from microscopy, SEM and related equipment.
* Contribute to high-quality publications and impact in the manufacturing sector.
Qualifications and Skills
* PhD (or equivalent) in materials science and engineering, physics, chemistry or a related discipline, with a strong experimental research background.
* Experience with characterisation and testing facilities such as microscopy, SEM, cavitation erosion and fatigue testing, micro/nano-indentation.
* Knowledge of data acquisition systems, acoustic pressure measurement in cavitating liquids, and high-speed filming is highly desirable.
* Strong communication skills, ability to work in a team, and proficiency in written and spoken English; track record of disseminating research outputs.
* Willingness to collaborate across institutions and visit partner locations as required.
Project Context
The project aims to develop bespoke aluminium alloys tailored for Additive Manufacturing, with a three-fold strategy: design hierarchically structured alloys, test performance in AM, and validate the approach by manufacturing AM test parts. The goal is a new class of high-quality AM materials with lightweight, uniform structure and properties, high rigidity, thermal stability, and designed functionality.
