We are looking for a PhD student for a research project on microscale mechanical characterization of fiber reinforced polymer composites using in-situ microscopic techniques. Much more fundamental insights and measurements at the micro-scale are necessary to enable fully predictive multi-scale modelling and faster adaptation of composites. Therefore, we have developed advanced micromechanical test methods for fibre reinforced polymer composites based on in-situ optical and electron microscopy during loading.

We seek a full-time Ph.D. student to work on the transmission electron microscopy (TEM) of nickel-based superalloys in the Department of Mechanical Engineering at the University of Alabama. The position will start in January 2021 and will be for four years. It will be funded through a new NSF project on surface engineering of the nickel-based superalloys. The goal is to explore and understand the strengthening and precipitate interactions.

A PhD position is available at LaSie (La Rochelle University, France), until oct. 2019.

The work will be dedicated to the caracterisation (numercial and experimental) of the effect of grains boundary on the Hydrogen diffusion in Nickel polycrystals.

Selection and thermal stability of phases are important in design of high entropy alloys (HEA). In this study, phase formations in cast AlFeCoNiCu HEA were investigated. Ab-initio molecular dynamics (AIMD) simulations were used to determine crystal structures of phases at different temperatures in equiatomic composition of AlFeCoNiCu. The AIMD results showed a possible coexistence of a face-centered cubic (fcc) phase and a bodycentered cubic (bcc) phase at the room temperature and indicated stabilization of a single fcc phase above 1070 K at the equiatomic composition of AlFeCoNiCu.
