  • The Kacher Lab is currently looking for a dynamic researcher to aid in our efforts to understand the multiscale microstructural effects dictating the mechanical behavior of materials. As a team, we explore how microstructure and processing conditions affect bulk properties and local failure mechanisms using multiscale and in situ-based electron microscopy techniques. Currently, we are accepting applications for a post-doctoral position focused on understanding dislocation mechanics at the micro to nanoscale under a range of loading conditions. The work will involve in situ TEM using a custom-built quantitative micromechanical testing platform and post mortem analysis of dislocation/grain boundary interactions. The position is available beginning in August 2020 and will continue for one year from hire date, with yearly extensions to a second and third year possible depending on performance and funding.

    Required Qualifications:

    • A Ph.D. in Materials Science and Engineering, Mechanical Engineering, Physics, or a related discipline.

    • Excellence in written and oral communication as evident by a strong publication and presentation track record.

    • Expertise in electron microscopy-based characterization

    Desired Qualifications:

    Strong candidates will have experience in at least some of the following areas:

    • TEM-based dislocation characterization


    • EBSD-based analysis of microstructure and defect structures
    • FIB-based TEM sample preparation
    • In situ TEM nanomechanical testing
    • Fatigue testing and failure analysis
    • Corrosion/stress corrosion cracking

    Interested candidates should send a cover letter, CV including a list of publications and presentations, three potential references with phone numbers and emails included to Prof. Josh Kacher (josh.kacher@mse.gatech.edu). Reviews of applications will begin immediately and will continue until the position is filled.

  • Start date: September / October 2020
    Locations: Grenoble (ESRF), Poitiers (PPrime), Paris (Ecole des Mines)

    Understanding the deformation processes leading to the failure of polycrystalline structural materials is one of the key challenges in materials science. Significant progress has been achieved over the past decades, thanks to both cutting-edge experimental characterization techniques and computational methods. Still, the localization of plasticity in slip bands and the propagation of plasticity through a polycrystalline aggregate are not fully understood. The French ANR research project 3DiPolyPlast aims at improving our understanding of the multi-scale processes involved in plastic deformation by combining experimental observations with concomitant numerical simulation of strain localization. 3DiPolyPlast unites four leading research institutes covering the fields of X-ray characterization, electron microscopy and crystal plasticity modelling, respectively.

    Topic 1) “Experimental study of plastic strain localization in polycrystals by 3D synchrotron X-ray diffraction imaging techniques” (ESRF, Grenoble & MATEIS INSA Lyon, France)  - Contact: Wolfgang Ludwig - ludwig@esrf.fr

    Topic 2) Experimental study of plastic strain localization in polycrystals by electron microscopy- based techniques” (Institute Pprime, Poitiers, France) - Contact: ludovic.thilly@univ-poitiers.fr

    Topic 3) Simulation of plastic strain localization by Discrete Dislocation Dynamics and crystal plasticity (CdM, Ecole des Mines Paris, France)”  - Contact: henry.proudhon@mines-paristech.fr

  • La Faculté des Sciences de Marseille propose deux postes d'Attaché Temporaire d'Enseignement et de Recherche (recrutement ATER).

    1er recrutement ATER:


    Comportement de films minces et de dispositifs de l'électronique souple sous sollicitation mécanique, élaboration de films minces thermoélectrique pour la récupération d'énergie.

    Détails du poste:

    La personne recrutée exercera ses activités de recherche prioritairement au sein de l'équipe MNO du département PHANO de l'IM2NP ou, à défaut au sein de l'équipe RDI du département  MATER de l'IM2NP.

    La personne recrutée développera des activités en science des matériaux avec une orientation tournée:

    1.  Soit vers l'étude du comportement mécanique des films minces et des dispositifs de l'électronique ou du photovoltaïque (PV) flexible (équipe MNO), via principalement  des expériences de diffraction des rayons X en rayonnement synchrotron (ESRF, SOLEIL, DELTA)
    2. Soit vers l'élaboration de films minces thermoélectriques non toxiques pour la récupération d'énergie dans les dispositifs microélectroniques (équipes RDI). 


    Plus d’information sur la durée du poste, la composante d'enseignement et les modalités d'application, sont disponibles dans le document téléchargeable suivant: « Fiche_de_poste_ATER_51831.pdf »

     2nd recrutement ATER:


    Imagerie de structure et de défauts dans des nano-objets sous sollicitation mécanique ou électrique.

    Détails du poste:

    La recherche portera sur l'étude de la structure (déformation, défauts,...) et des propriétés des nano-objets (nano-fils ou nano-plots) lorsqu'ils sont sous sollicitation, que se soit mécanique ou bien électrique. Pour cela nous utiliserons l'imagerie par diffraction cohérente des rayons-X en condition de Bragg (BCDI) ou bien l'imagerie à haute résolution par microscopie électronique en transmission (HR-MET).

    la technique BCDI est une technique particulièrement novatrice  qui permet de réaliser une image 3D des objets de petites tailles (quelques centaines de nm) pour révéler les variations de densité électronique et du champ de déplacement avec une résolution picométrique.

    Par ailleurs, un nouveau porte-échantillon acquis récemment pour le MET à haute résolution TITAN à St Jérôme permet de sollicter électriquement des nano-objects et d'imager la déformation in situ.

    De nombreuses données ont été collectées ces dernières années et des nouvelles expériences à l'ESRF et au TITAN sont prévues. L'analyse et la valorisation des ces expériences seront au centre de la recherche associé à ce poste.

    Plus d’information sur la durée du poste, la composante d'enseignement et les modalités d'application, sont disponibles dans le document téléchargeable suivant: « Fiche_de_poste_ATER_56224.pdf »

  • At the Max-Planck Institut für Eisenforschung  in the Department Structure and Nano-/Micromechanics of Materials (Prof. G. Dehm) they offer a PhD student position in:

    "Atomistic Computer Simulation of Grain Boundary Structure and Mechanics"


    Understanding how grain boundaries influence plasticity will lead to significant advances in material design. In the context of the department’s research, the overarching aim of this PhD project is to connect grain boundary structures in fcc metals to physical properties.

    Your tasks:

    Your tasks will be to employ molecular dynamics simulations combined with Monte Carlo techniques to predict grain boundary structures at an atomic level and to model their mechanical behavior. A part of the project will be focused on investigating the influence of alloying elements in order to work towards deriving grain boundary design principles for improved materials properties. All of the work is expected to be performed in collaboration with the experimental activities of the department.You have a Masters degree with good to excellent marks in Physics, Material Science, Mechanical Engineering, or a related field and you would like to work on challenging problems in Nano- and Micro-Mechanics and Materials Science. Some prior computer simulation or programming experience (especially with Python or C++) is advantageous.

    The working language at our institute is English; sufficient proficiency in English to communicate effectively on scientific topics is required.
