Investigation on the Sub-structure development in HSA6 alloys to maximise strength via Thermomechanical simulations

Applications are invited for a full time EPSRC Industrial CASE PhD studentship in research associated with the development of high strength Al-alloys in BCAST at Brunel University London and in collaboration with Constellium. The PhD studentship is for a period of four (4) years effective from the 1^st of October 2023. The successful applicant will receive an elevated annual stipend (bursary) of approximately £23,000 to start, plus payment of their full-time Home/EU tuition fees.

With the increasing demand for reduced fuel consumption and lowering CO2 vehicle emissions the production of lighter, stronger, safer and more fuel-efficient vehicles is more crucial than ever. Castellum’s high strength 6xxx series aluminum alloys play an important role in producing new age vehicles (especially EVs) by improving mechanical properties, substructure and texture of their final products using alloys with increasingly higher recycled content. Even though these alloys have high strengths and ductility there are systematic differences in strength reported for different extruded parts. These differences can be categorized by shape, thickness and extrusion ratio and have been directly linked to substructure developed during extrusions. However, there is a gap in the knowledge base on the reasons behind the structural development during extrusion processing. The major objective of the PhD project is the fundamental understanding of the deformation paths and the induced deformation mechanisms during extrusion of high strength 6xxx aluminum alloys and how these contribute to the development of final property profile. The research work involves using the recently installed Gleeble thermomechanical simulation system to mimic extrusion processing to understand the development of structure which may be characterized with the state-of-the-art electron microscopy facilities established with the centre and contribute to the development of next generation Al alloys.

BCAST is a specialist research centre focusing on light metallic material related research with an international reputation and hosts the national centre of excellence in liquid metal engineering (the EPSRC Future LiME Hub) and a UKRI Interdisciplinary Centre for circular metals. BCAST is well equipped with state-of-the-art facilities for solidification science, metal processing and materials characterization. We cover fundamental research, technological development and industrial applications in the field of solidification and processing of light metals. For more information see www.brunel.ac.uk/research/Centres/BCAST. The proposed research will use facilities for metal processing as well as the characterization facilities in the newly established future metallurgy centre to understand fundamental science behind an industrially relevant problem. The research conducted as part of this PhD programme will contribute to the activities of the Constellium University Technology Centre (UTC) established with BCAST and form part of the major strategic alliance between the two.
