PhD student ID06-HXM

Context & Job description

Thesis topic: Visualization of self organization of dislocations using an x-ray microscope

You will join a collaboration between the ID06 team at the ESRF and the departments of physics and mechanical engineering of the Technical University of Denmark (DTU) - SOLID - to study plastic deformation in metals. Beamline ID06 uses Dark Field X-ray Microscopy (DFXM), a newly developed hard X-ray technique for full-field imaging of phase, orientation and strain of crystalline volumes embedded within polycrystalline samples. The objective of the PhD project is to exploit DFXM to unravel how the patterning of dislocations is initiated when a pristine metal is deformed by 0-4%. You will perform in-situ experiments at ID06 and analyze the data.  A major task will also be to combine the 3D experimental movies with 3D movies from state-of-the-art dislocation simulations. This project is a key test of our understanding of how dislocations move and interact. It will thus provide the first-ever direct validation of the underlying assumptions used in the current modelling approaches.
