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, specifically focusing on the influence of quenching and pre-ageing on the performance of high strength 6xxx aluminium alloys. Hosted by the Department of Materials and in collaboration with Constellium, the project is part of the EPSRC Industrial Doctoral Landscape Awards (IDLA) and provides a unique blend of academic and industrial experience.

As the automotive industry continues its transition towards lightweight, 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 significantly 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 laboratory testing to study microstructural evolution during processing, with the goal of refining alloy design and extrusion practices for automotive applications.

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. The student will have access to state-of-the-art facilities and will work closely with leading academics and industrial experts, gaining exposure to industrial manufacturing environments through collaboration with Constellium.

Funding for this studentship includes an annual tax-free stipend set at the UKRI rate (£20,780 for 2025/26, subject to annual uplift), payment of full tuition fees for 4 years, and substantial extra maintenance provided by the industrial sponsor. The programme is open to both Home (UK) and overseas students, with a start date in October 2026. Applicants should hold or expect to achieve at least a 2.1 honours degree in materials science/engineering, metallurgy, physics, chemistry, or a related discipline. Relevant experience and a strong motivation for the project are desirable.

To apply, candidates should contact the main supervisor, Prof. Xiaorong Zhou, via email ([email protected]), providing details of their current level of study, academic background, relevant experience, and a paragraph outlining their motivation for pursuing this PhD. Early application is recommended as the advert may be withdrawn before the stated deadline of 31 January 2026.
