PhD student in 4D diffraction imaging of grain growth in metals
Investigate grain growth in polycrystalline metals using advanced 4D synchrotron diffraction imaging techniques.
Best for:Best for candidates with a background in materials science or physics and a strong interest in experimental X-ray science and computational data analysis.
Overview
The European Synchrotron Radiation Facility (ESRF) is offering a PhD position focused on 4D (3D + time) synchrotron diffraction imaging of grain growth in polycrystalline metals. Working within the 4DGG project, the successful candidate will utilize pink-beam topotomography at beamline ID03 to observe grain boundary migration in aluminum, iron, and nickel. This research aims to provide quantitative data to improve full-field grain growth models by correlating boundary velocity with curvature and elastic strain. The student will be enrolled at the Université Grenoble Alpes and will collaborate with partners at INSA Lyon and Mines Paris.
What you'll do
- Prepare polycrystalline aluminum, iron, and nickel samples for experimental analysis.
- Select target grains using 3DXRD and DCT techniques.
- Design and execute in situ high-temperature grain growth experiments at beamline ID03.
- Reconstruct and analyze 4D datasets to quantify grain boundary velocity, curvature, and elastic strain.
- Collaborate with research partners at INSA Lyon on topotomographic reconstruction.
- Provide experimental data to support full-field grain growth simulations at CEMEF.
- Publish research findings in peer-reviewed journals and present at international conferences.
- Write and defend a doctoral thesis at Université Grenoble Alpes.
