Full-funded PhD Studentship in Design of 3D printed alloys for medical implants
A full PhD studentship on alloy design for 3D printed medical devices is offered. The project is led by Dr Wei Wen (Advisor) and Professor Pedro Rivera (Principal Supervisor) at the Department of Engineering, Lancaster University, in collaboration with Carpenter Technology. This research will focus on the development of physical metallurgical principles and computational models for the design of medical implants such as knee and hip replacements. Simulation techniques at multiple length scale will be involved in this research. You will collaborate with colleagues at Lancaster University and Carpenter Technology partners, and will be actively involved in meetings, workshops and conferences.
There is a need to replace cobalt-based alloys for medical implants. Recent European regulations have banned the use of cobalt and its alloys due to health hazards. It is required to conceive new alloys displaying biocompatibility, cell viability, corrosion resistance as well as good mechanical behaviour. In addition to this, alloys must be printable offering the added benefit of tailored geometry. The project is part of a larger research collaboration with Carpenter Technology, aiming to enhance our current understanding of the processing-structure-property-performance relationships during additive manufacturing and develop a predictive alloy design and process optimisation strategy.
This PhD research will focus on computational modelling-inspired alloy design. Attractive alloys will be cast and atomised, and further printed and tested. The candidate will be required to numerically analyse the effects of chemical composition, powder production and selective laser melting (SLM) processes on the microstructure of the material. Physics-based thermodynamic and mechanics models will also be established to bridge the microstructure with macroscopic behaviour.
Qualifications and experience:
• The minimum academic requirement for admission is an upper second class UK honours degree at the level of MSci, MEng, MPhys, MChem etc, or a lower second with a good Master’s, (or overseas equivalents) in a relevant subject.
• Background in thermokinetics and physical metallurgy is required.
• Knowledge in crystal plasticity and dislocation theory is preferred.
• A good basis in computer programming is essential for the post.
• Excellent oral and written communication skills with ability to prepare presentations, reports and journal papers to the highest levels of quality.
• Excellent interpersonal skill to work effectively in a multi-disciplinary project area of research.
