Peter Hedström

Peter Hedström is a Professor of Materials Science at the Department of Materials Science and Engineering, KTH Royal Institute of Technology. He leads the Hultgren Laboratory for Materials Characterization and directs the Center for X-rays in Swedish Materials Science (CeXS) and the Vinnova competence center NEXT. His research focuses on advanced materials characterization, structure-property relations, and materials design, particularly in metallic alloys, steels, ceramics, and composites. He co-founded companies Ferritico and Scatterin based on his research. Hedström’s work leverages large-scale infrastructure like synchrotron and neutron methods, with key projects including ENDUREIT for improving duplex stainless steels and Track-AM for additive manufacturing analysis.

Education: PhD from Luleå University of Technology. Earlier roles at MEFOS/Swerim before joining KTH in 2008.

Research Interests: Phase transformations, materials characterization (e.g., synchrotron/X-ray/neutron techniques), additive manufacturing, machine learning applications, and fatigue mechanics. His group explores topics like low-temperature embrittlement, microstructure-strength relationships, and cemented carbide sintering.

Articles Trends: Recent work emphasizes in-situ observations of phase separation, precipitation kinetics, and microstructural stability under fatigue. Studies often integrate computational modeling with experimental methods, highlighting interdisciplinary approaches.

Grants/Projects: Directs CeXS (hosting the Swedish beamline P21 at PETRA III) and NEXT. Active in EIT Raw Materials (ENDUREIT) and MMD initiatives. Supervises PhD/postdoc projects in neutron scattering, Mg-AM, and machine learning.

Labs/Teams: Hultgren Laboratory, SwedNess graduate school, and collaborations with industrial partners like Ferritico.
