Job description:
The ESRF is a multinational research institute, situated in Grenoble, France and financed by 21 countries mostly European. It operates a powerful synchrotron X-ray source with some 30 beamlines (instruments) covering a wide range of scientific research in fields such as biology and medicine, chemistry, earth and environmental sciences, materials and surface science, and physics. The ESRF employs about 600 staff and is organized as a French société civile.
Within the Experiments Division, the X-Ray NanoProbe group is now seeking to recruit a:
PhD Thesis Student
Subject: Investigation by in-situ nano-tomography of cavities nucleation and growth in light alloys during high temperature deformation
fixed-term contract
GENERAL FRAMEWORK
In the context of environmental challenges such as the depletion of fossil resources, light alloys (e.g. magnesium or aluminium-based) are a solution for saving energy by reducing the weight of structures, in particular in the transportation sector for which it has become vital to reduce greenhouse gases emission. The synthesis of such alloys is highly dependent on their crystallographic structure and micro-structure in addition to the loading conditions. However there are voids or cavities nucleation, growth and coalescence during high temperature deformation which can degrade their formation. A deeper understanding of the relation between microstructure, loading conditions, deformation and cavities nucleation is a key point for the development of these new alloys. It is particularly relevant to follow this formation in-situ within specific environment and real time characterization at the nanoscale. In this context, hard x-ray nanotomography is a highly suitable method.
DESCRIPTION OF THE THESIS WORK
This thesis aims at :
• investigating damage initiation in light alloys during high temperature deformation using in-situ nano-tomography at the new hard X-ray nanoprobe beamline ID16B
• develop a tension/compression device compatible with the setup and perform high temperature in-situ nano-tomography under mechanical loading and will be strongly involved in the image data processing and analysis.
The project will be carried out in collaboration with the SIMaP laboratory which provides expertise in in-situ analysis at the micro-scale.

EXPERIENCE AND QUALIFICATIONS
• A degree in Physics, Materials Science or Chemistry allowing enrolment for a PhD, such as an MSc, Master 2 de Recherche, Laurea or equivalent
• English proficiency (the working language at the ESRF is English)
WORKING CONDITIONS
• Place of Work: ESRF in Grenoble
• Supervisors: Julie Villanova (ESRF) and Pierre Lhuissier and Luc Salvo (SIMaP)
• Contract of two years renewable (subject to satisfactory progress) for one year.
• Monthly gross remuneration: 2320 €.
