This project is designed to provide a physical metallurgy platform for understanding and interpreting the role of clusters of micro-alloying elements in precipitation in light alloys and aiding new alloy development. Phase transformations play an important role in determining the mechanical properties of many engineering materials.

Recent studies reveal that alternating electric or magnetic fields can rotate conductive nanofillers in polymers. This project aims to advance a new concept of aligning nano-scale reinforcements (for example, graphene nano-sheets and carbon nanofibres) along the thickness direction of composite materials. The alignment of nano-sized reinforcement will address the perennial problem of through-thickness weaknesses of fibre-reinforced composites and, at the same time, improve the electrical conductivity of composites. The synergistic improvements in the mechanical and electrical properties will improve damage tolerance and diagnosis of composites, thus expanding their applications in transport and civil construction to help reduce carbon dioxide emission.Read moreRead less

The microstructural damage accumulation stage often consumes a significant portion of the total fatigue life of structures. However, its progressive evaluation is beyond the reach of safety inspection techniques which are currently employed to maintain structural integrity and prevent fatigue failures.

The aim of this project is to develop a theoretical model that predicts grain size when components are cast under the influence of external fields (electromagnetic, ultrasonic, pulsed electric current and melt shearing treatments) and with the addition of nano-particle master alloys. Refining microstructures by available master alloys is reaching a limit and this limits further improvement in mechanical properties to meet the challenge of new applications requiring, for example, high temperature properties or light weighting (for example, use of less material). The outcomes will be a new theoretical model, validated numerical models, new casting technologies and highly refined alloys with greater than 25 per cent improvement in mechanical properties.
