Description

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.

Currently the focus is on three subjects:

  • 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. 
  • 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.
