Position: PhD Studentship: Design of strong and 3D printable aluminium alloy
Institution: University College London
Department: Department of Mechanical Engineering
Location: London, United Kingdom
Duties: This project will offer an exciting opportunity to design novel alloys for additive manufacturing combining cutting-edge computational and experimental methods. The research will initially revolve around developing Phase-Field and Thermodynamic models to study how material heterogeneities form during rapid-solidification; this understanding will be applied to later design compositions and processing conditions for improved performance, via reducing heterogeneities. Microstructural heterogeneities shall include elemental segregation, undesired secondary phases and hot cracking. The phase-field method is a compelling computational approach for predicting non-equilibrium phase transformation phenomena at a microstructural level. We are particularly interested in studying a new class of strong eutectic Al alloys and the project will require developing original phase field models for eutectic solidification
Requirements: Applicants should have (or expected to be awarded) an upper second- or first-class UK honours degree at the level of MEng, MSci (or overseas equivalents) in a relevant engineering or science subject, including materials science, engineering, physics, chemistry, applied mathematics or related disciplines

Studentship Description Transport accounts for 25% of global CO2 emissions and faces huge pressure to reach net-zero emissions by 2050. Additive Manufacturing -or 3D printing- of strong and light aluminium components for automotive and aerospace offers a sustainable solution by enabling the bespoke design of complex components using less material - therefore requiring less fuel. However, existing high-strength alloys are not suitable for additive manufacturing due to their high degree of heterogeneities during building and resulting poor mechanical performance. Therefore, new material concepts are necessary to design strong and 3-D printable aluminium alloys for realistic commercial deployment. This project will offer an exciting opportunity to design novel alloys for additive manufacturing combining cutting-edge computational and experimental methods. The research will initially revolve around developing Phase-Field and Thermodynamic models to study how material heterogeneities form during rapid-solidification; this understanding will be applied to later design compositions and processing conditions for improved performance, via reducing heterogeneities. Microstructural heterogeneities shall include elemental segregation, undesired secondary phases and hot cracking. The phase-field method is a compelling computational approach for predicting non-equilibrium phase transformation phenomena at a microstructural level. We are particularly interested in studying a new class of strong eutectic Al alloys and the project will require developing original phase field models for eutectic solidification. Having computationally developed novel alloys, these will be tested using a unique quad-laser additive manufacturing rig which has correlative ultra-fast x-ray, infra-red and optical imaging capability. The experiments will be carried out at Synchrotron Light Sources worldwide (e.g., ESRF France, APS Chicago), providing data to both perform fundamental and practical validation of the models. We offer a unique opportunity to collaborate with a highly interdisciplinary team of researchers using state-of-the-art techniques on material characterisation and computational modelling. The successful candidate will be encouraged to attend international conferences and publish high-quality papers to disseminate the outcomes of the project. The work will likely involve interacting with new and ongoing industrial partners to exploit the outcomes of the research. Person Specification Applicants should have (or expected to be awarded) an upper second- or first-class UK honours degree at the level of MEng, MSci (or overseas equivalents) in a relevant engineering or science subject, including materials science, engineering, physics, chemistry, applied mathematics or related disciplines.
