Abstract Scope |
Parts produced by additive manufacturing are widely used in aerospace and aeronautic fields and can experience several overloads leading to damage. Avoiding the replacement of damaged parts through a healing mechanism is of great interest. The goal of this research is the development of a modified high strength aluminium alloy able to heal its damage thanks to a liquid assisted strategy. In this alloy, a low melting point eutectic phase surrounds aluminium dendrites. During a heat treatment, the eutectic phase melts, goes inside cracks and porosities and weld them while cooling down. Addition of pressure with a hot isostatic pressing (HIP) improves the healing ability by helping to close porosities while the liquid phase fills them up. To study the healing ability, damage regions before and after healing were imaged with a voxel size of 35 nm by X-ray nano-holotomography technique at beamline ID16B ESRF. |
