Currently a doctoral student at the French Atomic Energy and Alternative Energies Commission (CEA), I am conducting my research at the Advanced Materials and Processes Research Department (SRMA). My thesis focuses on the development of a 13% Cr-4% Ni martensitic stainless steel using laser metal deposition. Thanks to my training in Chemistry and Materials Science (Master’s 1) and Materials for Sustainable Development (Master’s 2) at Claude Bernard Lyon 1 University, I have acquired solid skills in metallurgy, microscopy and the characterisation of the mechanical properties of materials. During my Master 2, I completed a research internship at CEA-SRMA on the evolution of the thermal and mechanical behaviour of silicon carbide (SiC) parts produced by Fused Filament Fabrication (FFF), as part of Maëlys Gauthé’s thesis dedicated to space applications, in particular space mirrors. My involvement focused on setting up experimental protocols and conducting tests, which led to me being cited as a contributor to the methodology and investigation in the scientific publication resulting from this work. I then moved on to metal additive manufacturing, pursuing a PhD in the same laboratory, the Laboratory of Extreme Materials Technology (LTMEx). The aim of my work is to explore the relationships between process parameters, microstructures and properties in order to optimise the quality and performance of parts produced using additive manufacturing for nuclear applications, particularly in pressurised water reactors (PWRs).
