PhD Position in Experimental Materials Physics: Synchrotron X-ray Studies of Additive Manufacturing of Tungsten
This PhD position at Helmholtz-Zentrum Hereon offers an exciting opportunity to join the Doctoral Network 'ElectronsMatter', funded by the Marie Skłodowska-Curie Action (MSCA) of the EU. The research focuses on the additive manufacturing (AM) of tungsten and tungsten alloys, materials crucial for energy, aerospace, and green technologies due to their exceptional properties. The project leverages electron beam powder bed fusion (PBF-EB) technology to process refractory materials like tungsten, overcoming challenges related to its high melting point and brittleness.
Based at the Hereon outstation at DESY in Hamburg, you will conduct experimental investigations using high-energy synchrotron X-rays to study transient behaviours during AM processes, such as molten pool dynamics and stress evolution. The MiniMelt sample environment, provided by network partners from KTH Stockholm, enables in-situ AM experiments in the X-ray beam. You will contribute to developing simultaneous radiography and diffraction measurement techniques, allowing imaging and diffraction data from the same sample volume.
As part of the European network, you will collaborate with other doctoral students and participate in training activities. Supervision is provided by Prof. Martin Müller (Christian-Albrechts-Universität zu Kiel) and Dr. Guilherme Abreu Faria. The position is full-time (39 hours/week), initially limited to three years, and offers a competitive EU-funded salary: €4,058/month living allowance, €710/month mobility allowance, and €660/month family allowance if applicable (gross figures, including taxes and social security contributions).
Applicants must have a Master's degree in physics, materials science, or a related discipline, with experience in X-ray diffraction techniques, research equipment, experimental research, programming, and large data analysis. Strong communication skills and proficiency in English are required. Additional assets include experience with synchrotron diffraction, metallurgy, specimen preparation, electron microscopy, computational modelling, and German language skills. EU mobility rules apply: candidates must not have resided or carried out their main activity in Germany for more than 12 months in the 36 months before recruitment, and must not already possess a doctoral degree. Willingness to be seconded to two project partners for one month each is required.
The Institute of Materials Physics at Hereon operates advanced instruments for structural investigations and develops novel light-weight materials for high-temperature applications. The research campus offers excellent infrastructure, networking opportunities, training, social benefits, and a family-friendly policy. Applications from qualified women and severely disabled persons are strongly encouraged.
To apply, submit your comprehensive application documents (cover letter, CV, transcripts, certificates, etc.) via the provided application link, indicating reference number 2026/WP 2, by May 10th, 2026. For questions, contact Dr. Peter Staron. Join a vibrant international research environment and contribute to cutting-edge materials science for a changing world.
