Third-cycle subject: Materials Science
Materials that can withstand extreme heat, pressure, and corrosion are essential for the energy, aerospace, and clean tech industries. Tungsten excels in all these areas, but its use is limited by its brittleness and very high melting point, which make it difficult to process with conventional methods.
Supported by the Marie Skłodowska-Curie Actions programme, the ElectronsMatter network is addressing this challenge through electron beam powder bed fusion, a cutting-edge additive manufacturing technique. By combining modelling, process optimisation, and advanced materials characterisation, the project aims to produce crack-free tungsten components.
The Department of Materials Science and Engineering at KTH is now recruiting two PhD students to join this European network, contribute to the research, and receive training in sustainable manufacturing and advanced materials.
Briefly about the two projects:
Microstructure modelling:
Develop thermodynamic and kinetic descriptions of tungsten and its alloys.
Integrate results into microstructure models to predict phase transformations and grain structure during electron beam powder bed fusion.
Collaborate closely with experimental researchers to validate models and contribute to crack-free tungsten components.
Advanced materials characterisation:
Characterise tungsten and its alloys at the atomic level using techniques such as atom probe tomography (APT) and electron-ion microscopy.
Focus on identifying and understanding the effects of trace and alloying elements on microstructure and properties.
Link experimental data with microstructure modelling to contribute to crack-free tungsten components.
Supervision: Greta Lindwall and Peter Hedström (subject to admission decisions).
Study in a dynamic and international research environment in collaboration with industries and universities worldwide.
Monthly salary according to KTH’s Doctoral student salary agreement.
Mobility allowance and possible family allowance under the Marie Skłodowska-Curie program.
Postgraduate education at an institution supportive of working conditions, gender equality, diversity, and study environment.
Work and study in Stockholm, close to nature and water.
Guidance on relocating and settling in at KTH and Sweden.
Opportunities to collaborate with academia, research institutes, and industry as part of the ElectronsMatter network.
International research training with secondments at partner universities and in industry, joint doctoral courses, and training schools.
Must meet basic eligibility for postgraduate education (Chapter 7, 39 § Swedish Higher Education Ordinance).
Mobility rule: Candidates must not have resided or conducted main activity in Sweden for more than 12 months in the 3 years preceding the recruitment date.
Completed a second-cycle degree (Master’s degree) or equivalent knowledge.
