Postdoc in Materials Science and Engineering

 

Are you intrigued by materials failure and seek an opportunity to resolve the microstructural reasons in quest for a potential cure? Fatigue during cyclic loading is overwhelmingly the dominant reason for materials deterioration. Repeated loading and unloading changes the internal microstructure and bring about local stresses in metallic materials. These internal stresses superimpose with external loads in a synergistic manner causing an accelerated microstructural evolution, initiation of fatigue cracks and ultimately failure. Recent experimental findings reveal that the maximum of the internal stress shows a phase shift and does not coincide with the maximum external load but occur later – strongly urging for reconsideration of their impact on cyclic deformation. The collaborative research project aims towards gaining insight in this phase shift, its origin, and consequences for the microstructural deterioration during fatigue. The post doc position offers participation in beam times and an outplacement for three months at Los Alamos National Laboratory.

Responsibilities and qualifications
Your focus will be on characterizing the microstructural evolution in an aluminum alloy during cycling loading in tension and compression. Additional to laboratory experiments, you will perform x-ray diffraction using synchrotron radiation applying high-resolution reciprocal space mapping in-situ while cyclic loading. Based on the data, you will quantify the microstructure and the development of internal stresses during individual tension compression cycles shedding light on the mechanical stress state and its evolution during load cycles causing fatigue in the alloy.

Your tasks will include:

• Mechanical testing (mainly cyclic deformation)
• Microstructural characterization by electron microscopy (mainly EBSD)
• Participation at synchrotron beam time (PETRA or APS)
• Analysis of x-ray diffraction data to extract information on microstructure and stresses
• Simulation of the mechanical behavior and microstructural evolution

You should have a solid background in material science and mechanical engineering, in particular materials characterization and mechanics of solids.

As a formal qualification, you must hold a PhD degree (or equivalent).
