LPBF of refractory metals, high-entropy alloys, and copper — process limits and microstructure control
Iain Todd is Professor of Metallurgy at the University of Sheffield and Director of the Sorby Centre for Electron Microscopy, one of the UK's leading facilities for microstructural characterisation of AM metals. He leads Sheffield's Mercury Centre, an AM research hub that bridges fundamental process science and industrial application. Todd is best known for his work on LPBF of refractory metals (tungsten, molybdenum) and high-entropy alloys (CrMnFeCoNi and derivatives), pushing the processability limits of materials that conventional PBF systems struggle to handle. A distinctive thread in his research is the design of novel alloy compositions specifically optimised for AM rather than adapting existing wrought alloys — an approach that has opened new performance space for structural and high-temperature applications. He is an active partner in the Henry Royce Institute for Advanced Materials.
