Teaching and Research: 

Prof. Hosemann is interested in experimental material science for nuclear applications. His main focus is on structural materials used for nuclear components (fission, fusion, spallation, etc.). His research focuses on developing a basic understanding of the materials degradation processes in a nuclear environment and resulting consequences to engineering application.

Current Research Focus: 
  • Small scale materials testing on irradiated and unirradiated structural materials for nuclear applications. It is the aim to reduce the necessary sample volume to a minimum in order to assess the materials state while investigating the basic effects of radiation damage. Short Video
  • Investigating new advanced structural materials concepts (e.g. oxide dispersion strengthened steels) for nuclear applications using accelerated materials testing via ion beam irradiations.
  • Liquid metal corrosion of structural materials for nuclear applications. Development of a fundamental understanding of the involved mechanisms will lead to the development of improved alloying concepts and system operating techniques to reduce the corrosion issue.
