Project Description

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.
