Research Assistant / Postdoc (m/f/d) - Deformation and damage mechanisms during high temperature exposure of AM metals

Salary group E 13 TVöD Temporary contract for 24 months Full-time / suitable as part-time employment

The Bundesanstalt für Materialforschung und -prüfung (BAM) is a materials research organization in Germany. Our mission is to ensure safety in technology and chemistry. We perform research and testing in materials science, materials engineering and chemistry to improve the safety of products and processes. At BAM we do research that matters. Our work covers a broad array of topics in the focus areas of energy, infrastructure, environment, materials, and analytical sciences.

We are looking for talented people to join us.

Additive manufacturing processes produce hierarchical microstructures in metals far from equilibrium, which, when subjected to mechanical load, differ greatly in their deformation and damage mechanisms from those of the conventional material variant. The mechanisms are not yet sufficiently understood (especially for high-temperature loading). The aim of the project is to clarify and quantify the relevant deformation and damage mechanisms of LPBF-manufactured 316L steel under high temperature and fatigue loading.

Your responsibilities include:
  • Determination and quantification of the relevant deformation and damage mechanisms of additive manufactured steel 316L at high temperature and fatigue loading
  • performance of fatigue tests (LCF)
  • Characterization of the microstructure using optical microscopy, SEM, EBSD and TEM with the aim of determining the interactions of the hierarchical microstructural elements with the deformation mechanisms as a function of temperature, time and loading level
  • Quantification of characteristic microstructural features such as subgrain size, dislocation cell size or wall thickness
  • Documentation of research results with presentations, reports and peer- reviewed publications / interdisciplinary exchange with the international research community
  • Your qualifications:
  • Very well completed scientific university studies (diploma/masters) as well as completed doctorate in materials science and engineering
  • Comprehensive knowledge of the mechanical behaviour and microstructure of metals (steels, Ni-based alloys) and deformation mechanisms (including high-temperature deformation)
  • Solid knowledge in the field of mechanical testing (especially fatigue testing)m
  • Extensive knowledge and practical experience in the field of microstructure investigation with light microscopy, SEM, EBSD and TEM
  • Proven publication activity in peer-reviewed journals
  • Business fluent English and good written and spoken German language skills
  • Good communication and Information behaviour, initiative/commitment, willingness and ability to make decisions, ability to work in a Team/willingness to cooperate as well as flexibility
  • We offer:
  • Interdisciplinary research at the interface of politics, economics and society
  • Work in national and international networks with universities, research institutes and industrial companies
  • Outstanding facilities and infrastructure
  • Flexible working hours and mobile working
  • Your application:

    We welcome applications via the online application form by15.07.2022. Alternatively, you can also send your application by post, quoting the reference number 164/22-5.2 to:

    Prof. Skrotzki will be glad to answer any specific questions you may have. Please get in touch via the telephone number +49 30 8104-1520 and/or by email to Birgit.Skrotzki@bam.de .

    BAM pursues the goal of professional equality between women and men. We therefore particularly welcome applications from women. In addition, BAM supports the integration of severely disabled persons and therefore especially welcomes their applications. With regard to the fulfilment of the job advertisement requirements, the application documents are examined individually. Recognised severely disabled persons will be given preferential consideration if they are equally suitable.

    The advertised position requires a low level of physical aptitude.
