Doctoral student in Advanced microscopy of Zr alloys for nuclear reactors

About the role

The research at the Division of Microstructure Physics focuses on experimental investigations of engineering materials using advanced characterization techniques. We mainly use electron microscopy, atom probe tomography (APT) and large scale facilities (synchrotron and neutron scattering). The research primarily deals with the relation between microstructure and properties, and how this relationship is influenced by processing and in-service degradation. Among the materials studied, steel, hard coatings, zirconium alloys and high entropy materials are central. The applications are often related to energy and sustainability. About the research project Nuclear fuel is enclosed in cladding tubes made from zirconium alloys. To improve reactor safety and economic performance, new alloys are continuously being developed. In this project, the corrosion behaviour of a novel zirconium alloy will be investigated to improve our understanding of the underlying corrosion mechanisms and support the development of next-generation materials. Advanced characterization techniques, including electron microscopy and atom probe tomography, will be used to study corrosion processes at the atomic scale. Who we are looking for The following requirements are mandatory: To qualify as a Doctoral student, you must have a Master's degree (masterexamen) of 120 credits or a Master's degree (magisterexamen) of 60 credits* in Physics, Chemistry, Materials Science or Mechanical Engineering. Strong written and verbal communication skills in English Experience in materials science *for students with an education earned outside of Sweden, a 4-year Bachelor's degree is accepted. The following experience will strengthen your application: Experience in electron microscopy and atom probe tomography Interest in nuclear technology

Responsibilities

• Take courses at an advanced level within the Graduate school of Materials Science or Physics ( https://www.chalmers.se/en/research/we-train-new-researchers/graduate-schools/ )

• The position generally also includes teaching on Chalmers' undergraduate level or performing other duties corresponding to max. 20 percent of working hours
• Investigate Zr alloy samples using electron microscopy, atom probe tomography, etc. to understand degradation phenomena like corrosion
• Contract terms
• The Doctoral student positions are fully funded from start.
• The position is a fixed-term appointment of four years, with the possibility to teach up to 20%, which extends the position up to five years.
• A starting salary of 35,725 SEK per month (valid from May 1, 2026).
• Doctoral studies require physical presence throughout the entire study period. A valid residence permit must be presented by the study start date; otherwise the admission may be withdrawn.
