M³ Nexus Thrusts
Sustainable Physical Metallurgy & Materials Science
Research Philosophy: The Materials–Manufacturing–Mechanisms (M³) Nexus
Materials define what we make. Manufacturing determines how we make it. Mechanisms explain why it performs.
Sustainable Physical Metallurgy and Materials Science is organised around the Materials–Manufacturing–Mechanisms (M³) Nexus, which is designing the right metallic materials, manufacturing them more sustainably, and understanding the mechanisms that govern their performance. The philosophy is expressed through the vision: Make Better Materials. Better Make Materials. Make Materials better.
1. Circular Materials Design & Impurity-Tolerant Metallurgy Make Better Materials
Make Better Materials by designing metallic materials around resources, performance and circularity. This thrust develops compositionally adaptive and impurity-tolerant alloys—including CCAs/HEAs, steels, aluminium, and titanium alloys that accommodate or exploit residual elements from secondary feedstocks. Alloy chemistry, phase constitution and microstructure are engineered for demanding structural, energy, health and multifunctional applications.
2. Scrap-to-Materials Transformation & Low-Carbon Processing Better Make Materials
Better Make Materials by transforming how metallic materials are manufactured. Scrap, residues and secondary resources are converted into high-value materials through melting, thermomechanical processing, powder metallurgy and additive manufacturing. Processing–microstructure relationships are engineered to reduce material, energy and environmental burdens while delivering reliable metals for structural, energy, health and multifunctional applications.
3. Data-Driven Materials Performance & Mechanisms Make Materials Better
Make Material Better by revealing and controlling the mechanisms governing metallic-material performance. Advanced characterisation, CALPHAD, DFT, molecular dynamics, finite-element modelling and machine learning connect composition, processing and microstructure to deformation, fracture, fatigue, creep, corrosion, wear and oxidation, enabling predictive optimisation of materials for structural, energy, health and multifunctional applications.
