Professor David Armstrong serves as Professor of Materials Science and Engineering at the University of Oxford and Fellow and Tutor at St Edmund Hall. His work focuses on developing materials for extreme environments including nuclear fusion reactors, aerospace systems, and energy storage applications through microstructural control and advanced mechanical characterization.
His educational background includes a first degree in Materials Science from St Anne’s College, Oxford and a DPhil from Corpus Christi, Oxford investigating micromechanical properties in copper and nickel alloys. This foundational work evolved into radiation damage studies during his Culham Centre for Fusion Energy Junior Research Fellowship.
Armstrong's research centers on mechanical behavior of materials under extreme conditions—high temperatures (jet engines, reactors), radiation exposure (nuclear facilities, space), and high stresses (batteries, geological systems). He develops novel testing methodologies for nanoscale mechanical properties up to 1300 K, collaborating with Rolls Royce, UKAEA, ESA, and Berkeley on fusion materials, aerospace components, and battery technologies. His work bridges fundamental micromechanics with industrial applications in energy systems.
Analysis of his 2023-2025 publications reveals dominant themes in nuclear fusion materials (tungsten, ODS steels), lithium battery interfaces, and ceramic composites for extreme environments. Methodologically, his group pioneers correlative microscopy combining nanoindentation, TEM, and atom probe tomography to study irradiation effects, high-temperature deformation, and interfacial degradation across length scales.
His scientific recognition includes:
- Culham Centre for Fusion Energy Junior Research fellowship (2009)
- Royal Academy of Engineering Research Fellowship (2013)
- Institute of Materials Minerals and Mining Grunfeld Memorial Award & Medal (2015)
As an educator, Armstrong teaches core mechanical properties courses across undergraduate years and leads Fusion CDT modules on nuclear materials. He supervises numerous doctoral students while serving on the EPSRC Fusion Advisory Board and CDT management board. Current grants support micro-engineering of alloys for nuclear environments and lithium-metal battery development through industry partnerships with Rolls Royce and MicroMaterials.
His research group operates advanced micromechanical testing facilities for high-temperature and irradiated materials, collaborating with UKAEA’s Culham Centre and European fusion laboratories on plasma-facing component development. Future work targets solid-state battery interfaces and radiation-resistant high-entropy alloys for next-generation fusion reactors.
