Project Description

Applications are invited for a full-time EPSRC Industrial CASE (iCASE) PhD studentship for the project “Synergetic effect of surface-active metallic additions on structure modification in aluminium alloys” at Brunel Centre for Advanced Solidification Technology (BCAST), Brunel University London starting from the 1st October 2020. BCAST is an internationally-recognised research centre for innovative and leading-edge research in the field of solidification and metal processing of light alloys. It hosts the National Centre of excellence in liquid metal engineering (Future Manufacturing LiME Research Hub) and the national scale-up facilities in liquid metal engineering (Advanced Metal Casting Centre, AMCC) and light metal processing (Advanced Metal Processing Centre, AMPC). The project is sponsored by Constellium, a global leading manufacturer of high-quality advanced aluminium products and systems.

Main current means to control structure in wrought Al alloys is by adding grain-refining master alloys with insoluble particles (borides or carbides). This produces substantial grain refinement but not necessarily affects the distribution of particles formed by impurities or main alloying elements. In this project we will develop an alternative way of controlling the growth morphology of primary and secondary phases based on the control of the surface energy by small additions of surface-active alloying elements. The scientific novelty of the project will be in the informed selection of additions based on advanced thermodynamic modelling and physico-chemical analysis; studying the mechanisms of structure control in Al alloys by surface-active metallic additions; and optimisation of their addition for specific purposes (primary, intermetallic, eutectic modification). Most advanced characterisation techniques including scanning and transmission electron microscopy will be used. The practical outcome of the project will be in developing new or modified wrought primary and/or recycled Al alloys for automotive industry. In the final stage of the project, pilot-scale casting of selected alloys will be performed followed by extrusion and mechanical testing.

The project will be part of the activities of the Constellium University Technology Centre (UTC) established with BCAST. You will be interacting daily with researchers in BCAST and with Constellium’s industrial research engineers. An industrial supervisor of the project will be appointed by Constellium. In this close collaboration lies the foundation for your promising career path to industry or acedemia.

Eligibility

This scholarship is only available for UK nationals, UK residents with indefinite leave to remain/settled status, or EU nationals who are legally residing in the UK for 3 or more years, not wholly or mainly for the purpose of receiving full time education.
Note that applications from ineligible candidates will not be considered or responded to.

You should have or expect to receive by the beginning of this PhD study a first degree (BSc) at 2:1 or above in a suitable engineering and science discipline, e.g. metallurgy, materials science, mechanical engineering, chemical engineering, chemistry, physics, etc. A MSc level qualification is desirable.

A strong background in physical metallurgy, materials science or chemistry is essential and experience in microstructural characterisation and phase analysis is desirable.
