• -PhD: "Study of elementary deformation mechanisms of multi-component metallic alloys (high-entropy alloys) with a body centered cubic structure."

    This thesis is incorporated within the framework of fundamental research on High-Entropy Alloys (HEAs) with a body centered structure (BCC) – new alloys whose name emphasizes their inherent high mixing entropies.

    The proposed thesis is dedicated to the study of refractory HEAs with a BCC structure. The main objective of the work is to examine the evolution of mechanical properties of solid solutions Nbx(HfTaTiZr)100-x with x ranging between 20 and 100 (at.%). The proposed strategy would lead to identify the impact of elementary substitutions in the solid solutions on the mechanical behavior of the processes materials. The evolution of underlying deformation mechanisms will be at the center of the study and mainly performed by in-situ Transmission Electron Microscopy (TEM).

    Thesis supervision: Jean-Philippe Couzinié (Associate Professor [accredited research director], couzinie@icmpe.cnrs.fr) and Frederic Mompiou (CNRS scientist [accredited research director], frederic.mompiou@cemes.fr).

    LSPM research team (CNRS, UPR3407, Paris 13 University) will also be partner of the study under the supervision of Guy Dirras (Professor, dirras@lspm.cnrs.fr).

    Desired candidate profile: He or she should demonstrate a solid background in Materials Science with an excellent ranking/level in their Master’s degree.

    Beginning of the thesis/funding : 2018, 1st October; Deadline for application: 2018, 31 May.

    The thesis will be held at ICMPE in Thiais, near Paris , with long stays at CEMES in Toulouse.

  • The JRC is offering a post-doc and a trainee  position:

    -Post-Doc (24 months): "Exploratory Research Project Novel Micromechanical Testing Methods for the Characterization of Nuclear Materials/μMech."

    Description:

    The main activity concerns the development of novel micromechanical tests based on the in-situ deformation of metallic membranes produced by microfabrication techniques. The aim of the project is to develop a new methodology, including sample preparation, measurement procedures and data treatment and analysis, for mechanical testing of structural materials for nuclear applications.

    The candidate will be in charge of performing micromechanical testing ex-situ (using a nanoindentation set-up) and in-situ (inside a SEM). As well, he/she will be responsible for post-test examinations by electron microscopy, analysing the data and reporting.

    More information are available in the following document: « CA_Petten_2018.pdf »

    -Trainee (5 months): "Acquisition and analysis of nanoindentation results."

    Description:

    Nanoindentation is a mechanical testing technique that allows extracting local information of the mechanical properties of materials, such as hardness and elastic modulus. The JRC is involved in several international projects addressed to develop new methodologies for nanoindentation testing in quasi-static and dynamic modes, at room and at high temperatures. In this context, we are looking for a trainee to assist in the operation of nanoindentation equipment to set-up experiments, program and launch data acquisition matrices. The candidate will also be requested to perform post-processing of data, prepare data analysis reports and store the data in a materials database. A significant amount of work will be carried out in the laboratory followed by statistical analysis.The trainee could be an undergraduate/master student or a PhD student who would like to do a stay.

  • Subject: Characterization and Modeling of Dopant Diffusion Under Process-Induced Stress.

    Description: 

    The aim of the PhD is to reliably predict the impact of manufacturing process-induced stress on junction profile modification and subsequent electrical parameters shifts on sub-micrometric electronic active devices. The job will involve physical and electrical characterization of dedicated, previously designed simple test structures with a view to assessing the nature and magnitude of mechanical stress and dopant diffusion. A critical review and improvement (if necessary) of state-of-the-art stress-dependent dopant diffusion models will pave the way to an accurate Technology Computer Aided Design (TCAD) simulation of realistic (that is, manufactured) electronic devices.

    It will be performed in strong partnership with STMicroelectronics.

    Candidate profile:

    The ideal candidate has a Master Degree in Material Sciences (or equivalent), a solid background in semiconductor physics, good communication skills and is proficient in written and spoken English.

    PhD Advisor: Pr. Olivier Thomas; Email: olivier.thomas@im2np.fr; Laboratory: IM2NP (http://www.im2np.fr/); Industry: STMicroelectronics, Rousset–France (http://www.st.com); Funding: CIFRE (3 years); Location: Marseille (France), Rousset (France)

    Applications should be sent by email to Prof. Olivier THOMAS (olivier.thomas@im2np.fr) and/or Dr. Roberto SIMOLA (roberto.simola@st.com)

    Deadline: June 1st,2018; Starting year: 2018

  • Un poste de post-doctorant est disponible au CIRIMAT à Toulouse en collaboration avec la société SAFRAN/Nacelles.

    Description:

    L'objectif de ce travail de post-doctorat vise à une meilleure compréhension et à une prévision de l'endommagement en fatigue de l'alliage après vieillissement. Pour ce faire, dans un premier temps les mécanismes d'endommagement en fatigue seront étudiés à partir d'une revue bibliographique et en exploitant les résultats d'essais de fatigue déjà réalisés au laboratoire (exploitation des courbes d'essais, caractérisation d'éprouvettes sélectionnées, essais complémentaires si nécessaire) et chez le partenaire industriel. Dans un deuxième temps un modèle prédictif de l'évolution de l'endommagement en fatigue, en fonction des conditions de vieillissement sera proposé. Ce modèle basé sur les mécanismes observés sera validé sur la base de l'ensemble des données expérimentales disponibles chez Safran Nacelles.

    Le poste sera disponible dès le mois de juin 2018 pour une durée de 18 mois.

    Envoyer un CV détaillé, une lettre de motivation, ainsi que des lettres de recommandation.

    N'hésitez pas à prendre contact (avant même une candidature formelle) :

    -Bernard Viguier; Bernard.viguier@ensiacet.fr (CIRIMAT)

    -Anne Mahieu; anne.mahieu@safrangroup.com (Safran Nacelles)
