CEA / LITEN is heavily invested in the additive manufacturing of metal parts using SLM process (Selective Laser Melting) to increase yields, quality and functionalities of parts.

In the field of aeronautics, additive manufacturing of aluminum alloy parts is of great interest but constrained by several physical parameters related to aluminum as high optical reflectivity, surface oxidation, and thermal conductivity.

In this context, the addition of nanofillers is a new way to optimize SLM process for example, to adjust powder optical absorption, thermal diffusion within powder bed, metallurgical composition and final mechanical properties of parts.

This innovative approach based on nanofillers involves to understand and define specifically the SLM parameters. The aim of this thesis is to study the impact of adding nanoscale particles in the powder bed by considering especially Al/Ti alloys.

This position is open until it is filled.
