Surface mechanical treatment by friction stir processing of additive manufactured aluminium alloy parts to improve mechanical behaviour
Researcher: Juan Guillermo Santos Macias
Supervisor(s): Aude Simar, Pascal Jacques

This research project aims at improving the mechanical behaviour of additive manufactured parts through a friction stir processing (FSP) surface mechanical treatment. This post-processing method significantly enhances ductility and is expected to also enhance fatigue resistance. Fatigue is a critical phenomenon in many applications, e.g. structural parts in the aerospace industry. More specifically, this research is focused on studying the effect of FSP on the microstructure (porosity and second phase size and spatial distribution) and mechanical behaviour (residual stresses and fatigue) of selective laser melting AlSi10Mg parts. Furthermore, in order to define an adequate FSP patterning strategy, the project will also feature an analysis of the influence of processing parameters through a chained thermal and microstructural model.

Aerostream and IAWATHA (additive manufacturing), LOCOTED (thermoelectrics)
Researcher: Camille van der Rest
Supervisor(s): Pascal Jacques, Aude Simar

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 thermoelectric materials, additive manufacturing and friction stir processing technologies. 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. Concerning additive manufacturing, the main contributions are on the characterisation and optimisation of the microstructures and the mechanical behaviour of Al parts obtained by Selective Laser Melting and the developpment of new materials for additive manufacturing. Again, the link between the process parameters and the final microstructure/properties is a key issue. Finally, 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.
