Details on funding and duration: The project « LAETICIA » (Ligne d’Accélérateur d’Electrons pour le Traitement et l’Investigation en Conditions d’Irradiation Adaptées) is funded by the Normandy Region via the Normandy Interest Networks (RIN Collaboratifs: Réseaux d’Intérêts Normands) and the European Union with the European Regional Development Fund (FEDER: Fonds Européen de Développement Régional).

Metallic alloys, irradiation, microstructure, atom probe tomography, electron microscopy

Presentation of the institution and context:
The Materials Physics Group (GPM) is a Research Unit (UMR) between the CNRS, the University of Rouen Normandy and the INSA of Rouen Normandy. The GPM is a research laboratory specialized in scientific instrumentation and the study and characterization of materials. The post-doctoral project will take place in the department “Metallurgy, Ageing and Mechanics” within the team ERMEN (Materials Under Extreme Conditions).

One of the research topics within the ERMEN aims to understand mechanisms of ageing under irradiation of steels used in pressurized water reactors (PWR), and to correlate the evolution of the microstructure with the evolution of mechanical properties.  As part of LAETICIA project, an irradiation chamber has been designed to irradiated materials with electrons under specific temperature and pressure conditions. Thus, LAETICIA offers the possibility to irradiate with electrons metallic alloys of industrial interest: alloys representative of bainitic steels used for PWR vessels and ferriticmartensitic steels, potentials structural materials for future reactors (Gen IV).

In both cases, it is important to understand mechanisms that govern the microstructural evolution under irradiation: this make possible to improve the life time of PWRs in the first case, and to optimize structural materials under development in the second case.
Irradiating these materials with electrons is an excellent complement to ongoing studies in the laboratory on neutron and ion irradiated materials. Electron irradiated microstructures will be characterized at atomic scale using GENESIS plateform in GPM (electron microscopes, atom probe tomography). Experimental results will be interpreted using numerical simulations at the same scale. Numerical simulations will be performed by EDF. Experimental results coupled with the modeling will allow to validate the efficiency of the irradiation chamber in one hand, and to understand mechanisms at the origin of microstructural evolution under irradiation in the other hand.

A batch of samples, representative of steels for nuclear reactors of generations II and IV will be electron irradiated during the second semester 2019.

Description of the actions:
The post-doctoral researcher will be in charge of the microstructural studies using atom probe tomography of sample before and after electron irradiation:
- Sample preparation with focused ion beam (SEM-FIB)
- Analyses of samples by atom probe tomography
- Data treatment
- Result interpretation

Transmission electron microscopy analyses could be envisaged depending on results obtained by atom probe tomography.
Results will be compared with already obtained data on similar materials irradiated with neutrons and/or ions.

Candidate profile:
The candidate, holder of a PhD thesis must have a background in material sciences and metallurgy. A candidate with experimental qualities in scanning electron microscope and/or atom probe tomography is mandatory.
Monthly gross salary between 2600 € and 2800 € according to experience
