Development of a high strength liquid assisted healable modified AlMg alloy produced by additive manufacturing
Abstract
Aluminium alloys produced by additive manufacturing are largely used in aerospace and aeronautical fields where damage may occur due to overloads experienced in service. Instead of replacing damaged parts and producing new one, materials able to heal their damage sites have great potential. This research aims at developing a new high strength healable Al alloy manufactured by Laser Powder Bed Fusion (LPBF). Alloying element is introduced into an Al-Mg alloy to form a high strength alloy through the formation of strengthening precipitates. An Al matrix surrounded by Mg-rich low melting point eutectic network, similar to a vascular network, composed the microstructure. Once damage nucleates, a healing heat treatment (HHT) with or without additional pressure (Hot Isostatic Pressing) is applied to trigger the melting of the low melting point phase which flows into the voids and seals them during solidification. The influence of the additional pressure on the healing efficiency is studied. In this work, the healing ability of the modified Al-Mg alloy, and the influence of pressure addition during HHT has been characterized in 3D by a correlative X-ray tomography and electron microscopy methodology. The damage regions before and after healing were imaged with a voxel size of 35 nm by X-ray nano-tomography technique at beamline ID16B ESRF. In a second time, according to the ESRF data, a specific sample sub-volume containing the healed damage has been further investigated using PFIB-SEM serial sectioning tomography and TEM analysis combined with EDX elemental material composition analysis.
