Abstract

In this paper, a characterization of an AlSiMg alloy processed by direct metal laser sintering (DMLS) is presented, from the analysis of the starting powders, in terms of size, morphology and chemical composition, through to the evaluation of mechanical and microstructural properties of specimens built along different orientations parallel and perpendicular to the powder deposition plane. With respect to a similar aluminum alloy as-fabricated, a higher yield strength of about 40% due to the very fine microstructure, closely related to the mechanisms involved in this additive process is observed.
Keywords: additive manufacturing (AM); direct metal laser sintering (DMLS); aluminum alloys; light microscopy; electron microscopy; mechanical characterization additive manufacturing (AM); direct metal laser sintering (DMLS); aluminum alloys; light microscopy; electron microscopy; mechanical characterization
