Abstract

See full text

The invention relates to a process for manufacturing a part (20) comprising a formation of successive solid metal layers (201 . . . 20n), superimposed on one another, each layer describing a pattern defined from a numerical model (M), each layer being formed by the deposition of a metal (25), referred to as a filler metal, the filer metal being subjected to an input of energy so as to melt and constitute, by solidifying, said layer, wherein the filler metal takes the form of a powder (25), of which the exposure to an energy beam (32) results in a melting followed by a solidification in such a way as to form a solid layer (201, . . . 20n), the method being characterized in that the filler metal (25) is an aluminum alloy comprising at least the following alloying elements:

    Si, according to a weight fraction from 4% to 20%;Fe, according to a weight fraction from 2% to 15%.
