Development of new casting aluminium alloys: composition, microstructure and mechanical properties
Applications are invited for our industrially funded PhD studentship in BCAST (Brunel Centre for Advanced Solidification Technology) for the project titled “Development of new casting aluminium alloys: composition, microstructure and mechanical properties”. Successful applicant will receive an annual stipend starting from £18,668 and increasing to £20,241 in the third year plus payment of their full-time tuition fees for a period of 36-months (3 years), starting on the 1st of October 2023.
Both international and UK home students are eligible for this studentship.
The Project
With the growing need for lightweight structures, improving strength and ductility of light alloys such as aluminium (Al) has become of paramount importance in industries. Micro-alloying is known to be one of the most effective strengthening strategies for Al alloys. Rare-earth and transition elements are effective elements and can strengthen Al alloys in three different ways. These are (1) grain refinement during casting, (2) precipitation hardening and (3) microstructural stabilization via recrystallization and grain growth inhibition. Despite their advantages, the industrial use of these elements has historically been limited due to high cost and difficulties in processing. However, they are expected to more widely used in the development of new Al alloys with in the next decade with enhanced awareness and improved more efficient extraction technologies and consequently decreased production cost. This PhD project is funded by an industrial partner, aiming to understand the effect of rare-earth and transition metallic elements on the microstructure and mechanical properties of casting Al alloys, through thermodynamics calculations and physical experiments. The project scope includes: (1) the effect of rare-earth and transition metallic elements on the microstructure and mechanical properties of new Al alloys and compositional optimization of the selected Al alloys; (2) microstructures and strengthening mechanisms under as-cast and heat treatment conditions; and (3) the mechanical properties of the Al alloys at room temperature and elevated temperatures.

Shouxun Ji - Prof. Shouxun Ji is currently a Professor at Brunel University London. He has been focusing on the development of lightweight materials and structures for the automotive industry, aerospace, powered tools, and other sectors. The main activities include purpose-developed aluminium alloys and magnesium alloys with improved ductility, strength (at ambience and elevated temperatures), modulus and thermal conductivity, and the hybrid structures using different materials and different joining techniques. He is also working on new materials and structures for special applications, such as materials for explosive cords and high strength casting materials for aircraft. His works have helped industrial partners to deliver several products in massive manufacturing. Recently, he worked with world leading company to develop magnesium alloys for small engine applications, which requires improved strength and thermal conductivity at room temperature and at elevated temperatures.
Prof. Ji have plenty experiences in high pressure die casting including die structure design, gating system design and optimisation, casting process and casting materials. He also worked extensively on other shaped-casting processes such as sand casting, gravity casting, low pressure die casting, semi-solid metal processing of rheo-die casting, rheo-extrusion, and rheo-twin roll casting. His previous works also included cast irons (spheroidal graphite cast iron and austempered ductile iron) and copper alloys.
Prof. Ji has published more than 130 papers in the peer-reviewed scientific Journals and more than 20 international patents. He is the member of three ISO technical committee and one BSI technical committee and the editorial member of three scientific journals.
