摘要：
Method for manufacturing an aluminium alloy part by additive manufacturing comprising a step during which a layer of a mixture of powders is locally melted and then solidified, characterised in that the mixture of powders comprises:
first particles comprising at least 80% by mass of aluminium and up to 20% by mass of one or more additional elements, and
second yttria-stabilized zirconia particles,
the mixture of powders comprising at least 1.5% by volume of second particles.
first particles comprising at least 80% by mass of aluminium and up to 20% by mass of one or more additional elements, and
second yttria-stabilized zirconia particles,
the mixture of powders comprising at least 1.5% by volume of second particles.
