This EPSRC Industrial Doctoral Landscape Awards (IDLA) PhD studentship at The University of Manchester offers a unique opportunity to research the optimisation of thermomechanical ageing processing in high strength 6xxx aluminium alloys, with a particular focus on the influence of quenching and pre-ageing steps. The project is conducted in collaboration with Constellium, a leading industrial partner, and is based in the Department of Materials.

As the automotive industry moves towards lightweight, high-performance materials, AA6xxx AlMgSiCu aluminium alloys are increasingly used for vehicle structures, including body-in-white and electrification applications. While thermomechanical ageing processes have advanced alloy performance, the critical steps of quenching and pre-ageing remain insufficiently understood. This research aims to fill that gap by employing advanced microscopy to study microstructural evolution during processing, ultimately refining alloy design and extrusion practices for automotive applications.

The project will investigate how quenching rate and pre-ageing steps affect microstructural evolution and performance of AA6xxx alloys processed via advanced thermomechanical methods. Key research questions include: the impact of quenching on precipitate formation and PFZs; how variations in alloy chemistry (Si, Mg, Cu) influence quench sensitivity and precipitation behavior; the role of pre-ageing conditions (temperature, duration, natural ageing time) in shaping microstructural response; and the correlation between microstructural features, mechanical properties, and corrosion resistance. Correlative accelerated laboratory testing and analytical electron microscopy will be central to the research.

The programme combines pioneering academic research with industrial experience, offering access to state-of-the-art facilities and opportunities to develop interdisciplinary skills. The student will work closely with industrial collaborators at Constellium, gaining exposure to manufacturing environments and benefiting from substantial extra maintenance provided by the sponsor in addition to the standard EPSRC stipend.

Eligibility requires at least a 2.1 honours degree in materials science/engineering, metallurgy, physics, chemistry, or a related subject. Applicants must submit transcripts, certificates, CV, a supporting statement outlining motivation and relevant experience, and contact details for two referees with official email addresses. An English language certificate is required if applicable. Flexible study arrangements, including part-time options, may be considered.

The studentship is open to Home (UK) and overseas students, with an annual tax-free stipend set at the UKRI rate (£20,780 for 2025/26, subject to annual uplift), and full tuition fees paid. The expected start date is October 2026, and applications are accepted year-round. Early application is recommended as the advert may be removed before the deadline.
