Vacancy No. 741/2022

Postdoctoral Research Assistant (f/m/d)

Micromechanical characterization of grain boundary slip

Job description

The Institute for Applied Materials – Mechanics of Materials- and Interfaces (IAM-MMI) at the Karlsruhe Institute of Technology (KIT) strives for a fundamental understanding, prediction and optimization of mechanisms responsible for the degradation of advanced functional material systems. Our material portfolio comprises, among others, materials required for the energy transition, i.e. for energy conversion and storage as well as advanced structural materials.

Within the next three years, the successfull candidate shall develop a fundamental, quantitative understanding of grain boundary sliding in model materials using experimental micromechanics. Two main experimental techniques will be used:

  • Micro pillar manufacturing using a state-of-the-art focused ion beam microscope (FIB). The FIB is equipped with a femtosecond laser or low damage laser ablation
  • In situ small scale mechanical testing at non-ambient temperatures usind a field emission scanning electron microscope (SEM) equipped with a high temperature nanoidenter.

Through the combination of aforementioned techniques with data processing (e.g. digital image correlation), the shear stress vs. shear strain behavior of a single grain boundary should be measured at the micron scale for the first time.

Personal qualification

Candidates must have a university degree (diploma (Uni) / Master) with a PhD focus on physics, materials science or mechanical engineering. Experiences in microstructural properties of materials, electron microscopy and mechanical testing are beneficial.

Salary category 13, depending on the fulfillment of professional and personal requirements.
