PhD Studentship: Optimisation of Thermomechanical Ageing Processing in High Strength 6xxx Aluminium Alloys The University of Manchester in United Kingdom

[Annual tax-free stipend at UKRI rate (£20,780 for 2025/26, subject to annual uplift), plus full tuition fees for 4 years. Additional maintenance provided by industrial sponsor.]

This fully funded 4-year PhD studentship at The University of Manchester offers an exciting opportunity to advance research in the optimisation of thermomechanical ageing processing, focusing on the influence of quenching and pre-ageing on the performance of high strength 6xxx aluminium alloys. The project is based in the Department of Materials and is conducted in collaboration with Constellium, providing a unique blend of academic and industrial experience.

As the automotive industry moves towards lightweight and high-performance materials, AA6xxx AlMgSiCu aluminium alloys have become the preferred choice for vehicle structures, including body-in-white and components for both on- and off-road vehicles. While optimised thermomechanical ageing processes have improved alloy performance, the critical steps of quenching and pre-ageing remain insufficiently understood. This research aims to fill that gap by leveraging advanced electron microscopy and correlative accelerated laboratory testing to study microstructural evolution during processing.

The project will investigate how quenching rate and pre-ageing steps affect microstructural evolution and the resulting mechanical and corrosion properties of AA6xxx alloys. Key research questions include: the impact of quenching on precipitate formation and precipitation-free zones (PFZs); the influence of alloy chemistry (Si, Mg, Cu) on quench sensitivity and precipitation behaviour; the role of pre-ageing conditions (temperature, duration, natural ageing time) in shaping microstructural response; and the correlation between microstructural features and alloy performance.

Students will have access to state-of-the-art facilities and work closely with leading academics and industrial experts. The collaboration with Constellium offers exposure to industrial manufacturing environments and the opportunity to develop interdisciplinary skills in a team setting. The studentship includes an annual tax-free stipend at the UKRI rate (£20,780 for 2025/26, subject to annual uplift), full tuition fees for 4 years, and substantial extra maintenance from the industrial sponsor.

Eligibility requires at least a 2.1 honours degree in materials science/engineering, metallurgy, physics, chemistry, or a related subject. Applicants should provide details of their academic background, current level of study, relevant experience, and a motivation paragraph. The start date is October 2026, and early application is recommended as the advert may be removed before the deadline.
