Marion Auffray is a PhD researcher in Materials Science, currently based at LAMPA—the Angers laboratory of the Arts et Métiers Institute of Technology. Her research primarily investigates the fatigue behavior of metallic alloys through both experimental and numerical approaches. After earning a bachelor’s and master’s degree in general engineering with a specialization in mechanics and advanced materials, her doctoral work has focused on decorrelating the effects of surface condition, defects, residual stresses, and microstructure on the fatigue strength of 316L stainless steel produced via Laser Powder Bed Fusion additive manufacturing.
