PhD thesis: High-Cycle Fatigue of components repaired using Directed Energy Deposition.



Abstract :


Due to the rising price of energy and the scarcity of metal resources, the repair of metal parts is of paramount importance for many industries. Directed Energy Deposition (DED), an additive manufacturing process, allows to locally repair worn parts for repair. As for any manufacturing or repair process, the microstructures induced by DED are very dependent on the parameters chosen and these microstructures have a direct impact on the mechanical properties obtained. This thesis will focus on the link between microstructure and fatigue performance of repaired parts. This aspect still little mentioned in the literature is however a prerequisite for the deployment of repair by DEDon a large scale. An experimental part on repaired specimens will be used to characterize the microstructure in the repaired zone and to identify the damage phenomena responsible for HCF failure. In order to describe the microstructure at the interface between the initial part and the repaired area, a gradient fatigue criterion will be calibrated via a dialogue between experimental results and simulations.
