Postdoc in X-ray and Neutron Characterization of Metals for Additive Manufacturing KTH Royal Institute of Technology in Sweden

The Department of Materials Science at KTH Royal Institute of Technology is offering a postdoctoral position in X-ray and neutron characterization of metals for additive manufacturing (AM). The project focuses on in-situ and ex-situ synchrotron and neutron studies of metallic materials processed by laser- and electron-beam-based techniques, with particular emphasis on AM, welding, and heat treatment.

The work is centered on the custom-built experimental environment at the Swedish beamline at PETRA III, beamline P21.2, where electron-beam and laser processing can be studied in real time under controlled conditions. The postdoctoral researcher will help further develop the methodology for using this setup in collaboration with internal and external partners, generating new knowledge on metal behavior under rapid thermal cycles and on the resulting microstructure and properties.

The role also includes complementary characterization work to build a comprehensive picture of phase transformations, melt-pool dynamics, solidification, and end-use material behavior, including quasistatic or cyclic loading. The project combines advanced in-situ experiments with ex-situ analyses to better understand how processing conditions affect microstructure evolution and mechanical properties in metallic materials.

This position is highly relevant for researchers interested in advanced characterization, beamline-based experiments, additive manufacturing, welding metallurgy, and the development of sustainable materials and processing solutions. The research contributes to circular material flows, reduced scrap, and greater use of recycled raw materials, with applications in manufacturing and energy-producing sectors.

Applicants must hold a doctoral degree or equivalent foreign degree in materials science or a closely related area by the time the employment decision is made. The ad asks for demonstrated research experience in synchrotron light and neutron characterization, including diffraction, WAXS, SAXS, ND, SANS, and imaging, supported by publications and conference presentations. Excellent English skills are required, along with self-motivation, initiative, analytical ability, problem-solving skills, responsibility, and strong collaboration skills.

Preferred qualifications include a doctorate earned within the last three years, extensive data analysis experience for synchrotron or neutron studies of metallic materials, experience with electron-beam and/or laser processing, knowledge of mechanical behavior, phase transformations or precipitates, and lab-scale techniques such as SEM and XRD.

The position is a full-time temporary appointment for up to two years at KTH Royal Institute of Technology in Stockholm, Sweden. Applications must be submitted via KTH’s recruitment system by 2026-09-17. The application should include a CV, degree documents, translations if necessary, and a short statement describing research motivation, academic interests, and future goals.
