Laser Powder Bed Fusion (L-PBF) has focused the interest of the scientific and industrial communities over the past few years. Indeed, 3D printed alloys display many specific characteristics. Among all aluminium alloys, some of them, mainly structural grades, are suffering from the hot cracking problem during L-PBF processing. Severe thermal conditions associated with the process (high thermal gradient and high cooling rate) often induce columnar grain growth, a structure particularly prone to hot cracking phenomena. A general methodology to solve this issue was developed during the thesis, focusing on the grain structure downsizing, trying to promote small equiaxed grains. To this end, an Al6061 alloy powder commonly used in the aeronautic...
