Advanced characterization of new high-strength ultrafine-grained alloys using spinodal decomposition

This post-doctorate is part of the ANR SpinodalDesign project. It involves three French groups: the GPM (Groupe de Physique des Matériaux – UMR 6634, host laboratory for this post-doctorate), the UMET in Lille and SIMAP in Grenoble. In the framework of this project, we are developing an original way of achieving high mechanical strength by combining an ultra-fine granular structure and spinodal decomposition. The post-doctoral fellow will conduct a microstructural characterization of new high-performance alloys hardened in this way. Analyses will be carried out mainly by transmission electron microscopy and Atom Probe Tomography. She/he will also strongly interact with two PhD students in their second year.

The post-doctoral fellow will carry out the following tasks:
-    Literature review on the subject.
-    Planning of experiments to be carried out in collaboration with project partners (including PhD students from the two other labs).
-    Sample preparation using SEM/FIB
-    Characterization of samples by TEM, in particular using the ACOM TEM tool.
-    Atom Probe Tomography characterization.
-    Papers and conference presentations.

The following skills are expected:
-    Expertise in physical metallurgy.
-    Strong technical skills in one or more of the following characterization techniques: SEM/FIB, TEM/STEM or APT.
-    Fluency in English.
-    Strong organizational skills and ability to work as part of a team.

The candidate will follow training courses in Atom Probe Tomography (annual international school hosted by the GPM laboratory), and will also be trained in the use of SEM/FIB and TEM/STEM techniques through in-house training courses.

This post-doctorate is part of the ANR SpinodalDesign project. It involves the GPM (host laboratory for this post-doctorate), the UMET in Lille and SIMAP in Grenoble. The GPM (Groupe de Physique des Matériaux, UMR CNRS 6634) is organized into 5 departments: Materials-Ageing-Mechanics, Scientific Instrumentation, Nanosciences, Disordered Systems-Polymers and NanoHealth-Physics. It has a staff of 160, including 60 lecturers/researchers, 30 technical staff and 70 PhD students/postdoctoral fellows/trainees. The laboratory is located on the Rouen Normandy Science and Engineering Campus (Rouen), within the Université de Rouen Normandie and INSA Rouen Normandie (7000m2). The researcher recruited will be attached to the Science and Mechanics of Materials department within the Microstructures team.

Duration: 12 to 18 months (starting the sooner)
