Abstract

Method for manufacturing an aluminium alloy part by additive manufacturing that includes a step in which a layer of a mixture of powders is locally melted then solidified, wherein the mixture of powders includes: first particles that include at least 80 wt. % aluminium and up to 20 wt. % one or more additional elements, and second particles of ZrSi2, the mixture of powders including 1.8 wt. % to 4 wt. % second particles.
