Our group studies how processing controls microstructure and properties in metals, with emphasis on additive manufacturing and sustainable routes. We integrate in situ characterization (synchrotron X-ray diffraction/imaging, SEM/TEM) with physics-based modelling (dislocation thermomechanics, polycrystal thermo-elasto-viscoplasticity) to connect process → microstructure → properties. When tools don’t exist, we build them; custom instruments—a miniature AM device for synchrotron X-ray studies and a high-vacuum continuous-wave (CW) LaserSEM for oxidation-free surface processing (two patent applications filed)—let us track melt pools, phase changes, dislocation evolution, and residual stresses in real time; these datasets inform our micro-thermomechanical models. We use this experiment–modelling synergy to design energy-lean processes such as in-process laser heat treatments and high-vacuum laser surface treatments that improve strength, ductility, and fatigue limit.
