• Chalmers University of Technology is looking for a Postdoc in In-situ experimental micromechanics :  

    Department description:

    Stimulated by major needs and challenges in science and a sustainable society, the ambition of the department of Physics is to foster a creative environment for academic research, learning and outreach. We provide a competitive advantage by linking our top-level international and interdisciplinary academic performance in the areas of material science, nanotechnology and energy research with world-leading industrial R&D&I projects. We address a wide array of experimental, computational, methodological and theoretical challenges, from fundamental physics research, through the development of new materials such as graphene to direct industrial projects generating new inventions. We have a strong learning commitment on all levels from undergraduate to PhD studies where physics meet engineering. We are situated in a stimulating and creative environment with newly renovated facilities. The department is the major part of Gothenburg Physics Centre – a collaboration between five departments at Chalmers and Gothenburg University.

    Information about the project:

    The research at the Division of Materials Microstructure is concerned with the relationships between the structure and properties of materials. The main focus is on detailed characterization of the microstructure using advanced microscopy and micro-analytical techniques, but we are rapidly expanding in the fields of micro-mechanical testing as well as neutron and synchrotron X-ray scattering. As a post-doctoral researcher at the division, you would be expected to push the frontline of our state-of-the-art characterisation capabilities through the development, validation and application of novel in-situ micromechanical testing methods in scanning electron microscopes (SEM).

    In contrast to traditional micromechanical testing methods, which are usually based on in-situ nanoindenters with only linear (1D) actuation, you will use so called "micromanipulators" in order to deform and manipulate microscale specimens mechanically in three dimensions while recording forces and displacements. Micromanipulators are best described as small robots designed for operation within the SEM vacuum chamber and offer unconstrained movement in three dimensions in combination with force measurement using self-sensing piezoresistive cantilevers or spring tables and image analysis. They therefore present exciting new possibilities for mechanical characterisation of materials on the micrometer scale, but to realise these possibilities new methods have to be developed and validated.

    The work will include: (i) modelling of the micromanipulator set-up, including explicit response of the piezoresistive sensing, using finite element software (primarily COMSOL Multiphysics, but other software can be used depending on the experience and preference of the selected candidate); (ii) development and validation of novel test methods combining microscale specimen preparation using focused ion beam (FIB) milling and creative use of the unrestricted motion of the micromanipulators; and (iii) application of the developed methods for advanced in-situ micromechanical testing covering a range of material systems.

    Major responsibilities:

    Your major responsibilities are to pursue your own research project. You will also be expected to contribute to other research projects and activities in the division. Supervision of PhD and/or MSc students can also be a part of the work.

    Position summary:

    Full-time temporary employment. The position is limited to a maximum of two years (1+1).


    To qualify for the position of postdoc, you must have a doctoral degree in materials science, engineering, physics, or similar. The degree should generally not be older than three years. Experience of focused ion beam (FIB) milling and scanning electron microscopy is required. Knowledge of finite element modelling is highly meritious, as is experience of transmission electron microscopy. Knowledge of mechanics of materials is a benefit. We expect you to have the ability to work independently as well as in a group and to have good communication skills, including fluency in written and spoken English. Chalmers offers Swedish courses.

    Chalmers continuously strives to be an attractive employer. Equality and diversity are substantial foundations in all activities at Chalmers. 

    Application deadline: 16 December, 2018

  • The 2018 Mecano School held at IESC in Cargèse (Corsica) ended this friday Nov 2nd. The Adrian storm impacted the school (especially Prof. Thomas and Kiener's lectures), but certainly less than the local harbour of Cargèse

    Overall, about 40 presentations (posters, regular talks and posters) were given during the week.  The slides of the lectures can be found following the "Tutorial" link on the conference site.

  • A 12 months post-doctoral position is available in SIMaP in partnership with Institut Néel in Grenoble.

    Title: "Optimal compositions for Multicaloric materials: ferromagnetic memory shape alloys (NiMnXY)"

    Project: The project aims at developping new compositions for ferromagnetic shape memory alloys with multifunctional properties enabling new energy conversion process (mechanical / magnetic). These materials target energy reduction scheme for cooling devices (multicaloric properties (magneto/elasto)). Heusler based alloys NiMn(InX, X=Co, Cu, Fe...) exhibit exceptional properties, including the absence of rare earth elements. Multicaloric effects and the phase transition temperature (close to room temperature) are very sensitive to alloy composition. Dissipation during hysteresis cycle have to be decreased. These dissipations are due to structural effects allowing lattice strain accomodation between the phases during the (austenite-martensitic) transformation. Moreover, intermetallic NiMnXY phases are very fragile (grain boundary decohesion) and difficult to shape (lack of crystal plasticity and strong anisotropy of properties).

  • The 2018 Mecano school is going on in Cargèse (Corsica). Despite the passage of storm Adrian which interrupted the lectures for a few hours, those have resumed, safely.

    Tutorials are accessible for participants and on request from the Mecano network  on the conference website (Tutorials) or directly at https://mycore.core-cloud.net/index.php/s/QP4LegLI7mLmo4S  (password needed).

  • Title: "Fatigue damage in titanium alloy. Experimental Characterisation and Modelling."

    A post-doctoral position (18 month) is available in CIRIMAT Toulouse, in a collaborative framework with SAFRAN Nacelles. This position is related to a PhD study conducted in CIRIMAT on the evolution of microstructure and mechanical behaviour of a titanium alloy after ageing at high temperature under air.


    The project for this post doctoral position aims to better understand and predict fatigue damage after ageing. Damage mechanisms in this Ti alloy will be first studied through a literature survey and by the analysis of fatigue tests results already performed in the laboratory (analysis of fatigue curves, characterisation of ruptured specimens, complementary fatigue tests is necessary)and in the industrial partner. A predictive numerical model for the evolution of fatigue damage depending on ageing conditions will then be developed. This model, based on observed mechanisms, will be calibrated using experimental available in Safran data bases.

    Position is already open, send Curriculum and recommandation letters to:

    Bernard Viguier - Bernard.viguier@ensiacet.fr - CIRIMAT

    Anne Mahieu - anne.mahieu@safrangroup.com - Safran Nacelles
