Non-destructive characterization of Al alloys produced by additive manufacturing using correlative tomography

Parts produced by additive manufacturing are increasingly widely used and envisaged in various applications, including aerospace and aeronautics. However they can suffer from intrinsic fabrication defects (lack-of-fusion, keyholes, gas pores,…), as well as in-use damage. Avoiding the replacement of damaged parts through a healing mechanism is of great interest. Designing self-healing Al alloys is challenging because it requires appropriate temperature conditions, which can trigger the diffusion and/or local melting process of the healing agent. Proper understanding of the healing mechanism, followed by the healing treatment optimisation depends on a successful microstructural analysis performed at the exact location of a damage. Therefore, a multiresolution and multimodal imaging approach with a spatial resolution from micro- to nano- scale is required to evidence the microstructure healing efficiency.
