About

Welcome to the Alloy Design & Phase Transformations Research Group. We explore the fundamental mechanisms governing atomic movement and rearrangement in solids under the influence of composition, stress, and temperature, unlocking transformative changes in microstructure and material behaviour. Combining chemistry and process design with advanced characterisation and mechanical testing, we link microstructural evolution to real-world performance. We also harness the power of machine learning to accelerate alloy discovery and optimisation, bridging data science with materials engineering. Our mission is to create reliable, high-performance alloys that push the boundaries of what's possible in modern materials science.

SEM of partial bainitic transformation, formed after transformation at 250°C for 10 h (a) with NiAl. The arrow indicates the intragranular nucleation of bainite from the NiAl precipitates. (b) Without NiAl, nucleation is from the austenite grain boundaries.
