Thesis title: Thermal fatigue of metallic lattices produced by SLM

Titre de thèse: Fatigue thermique d'un réseau métallique produit par SLM

Thesis description: The powder bed additive manufacturing process as SLM is a complex phenomenon as metallic powder passes from a solid state through a liquid one to a new solid state with interactions between laser and material. The effect of the thermomechanical process on the mechanical behaviour takes place at two scales: (i) the microstructural scale where grain sizes, morphologies and orientations are depending on the process parameters  and (ii) the macroscopic scale where the successive heating-cooling processes associated to each powder layer introduce residual stresses due to strain incompatibilities. In this work, metallic lattices produced by SLM are investigated, in particular under cyclic loadings at different temperatures.

Keywords: Fatigue, LCF, additive manufacturing, SLM, lattice structure
