Camille van der Rest completed her PhD thesis on the optimisation of Heusler Fe2VAl-based thermoelectric compounds through innovative metallurgical processing in 2015. It was under the joint supervision of Prof. Pascal Jacques and Prof. Aude Simar. Her research topics now concern additive manufacturing, friction stir processing and thermoelectric materials.
Concerning additive manufacturing, the main contributions are on the characterisation and optimisation of the microstructures and the mechanical behaviour of Al parts obtained by Laser Powder Bed Fusion and the developpment of new materials for additive manufacturing. The link between the process parameters and the final microstructure/properties is a key issue. The optimisation of the post-treatments, both thermal treatments and Friction Stir Processing (FSP), is another of her research topics in order to reach improved mechanical properties. Finally, multi-material additive manufacturing is also studied, in order to understand the influence of both metallic alloys and their interactions (diffusion, reaction,...) on the final microstructures and properties.
On another hand, Camille developed, together with Prof. Aude Simar and Prof. Pascal Jacques, a novel Friction Melt Bonding (FMB) process in order to weld aluminium alloys and steels. This process is still under development thanks to the collaboration with other researchers of IMAP.
Concerning thermoelectrics, the main objective is the development of low-cost, non-toxic, and powerful materials that could be used in large-scale industrial applications of heat recovery. In addition, she studies some fundamental aspects in order to improve the performances of such materials, i.e. ordering phenomena in off-stoichiometric Fe2VAl-based Heusler compounds. It is essential to make the link between (innovative) manufacturing processes, microstructures and the functional properties of these TE materials.
