The invention relates to a process for manufacturing a part (20) comprising a formation of successive solid metal layers (201…20n), superposed 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 filling metal, the filling metal being subjected to an input of energy so as to melt and form, by solidifying, said layer, in which the filling metal takes the form of a powder (25), the exposure of which to an energy beam (32) results in melting followed by a solidification so as to form a solid layer (201 …20n), the process being characterized in that the filling metal (25) is an aluminum alloy comprising at least the following alloying elements: Si, in a weight fraction of from 4% to 20%; Fe, in a weight fraction of from 2% to 15%. The invention also relates to a part obtained by this process. The alloy used in the additive manufacturing process according to the invention makes it possible to obtain parts having remarkable mechanical performance, while obtaining a process that has an advantageous productivity.
The present invention relates to a process for manufacturing a part (20) comprising a formation of successive metal layers (201…20n), superimposed on one another, each layer describing a pattern defined from a numerical model, each layer being formed by the deposition of a metal (15, 25), referred to as filling metal, the filling metal being subjected, at a pressure greater than 0.5 times the atmospheric pressure, to an input of energy so as to melt and constitute said layer, the process being characterized in that the filling metal is an aluminium alloy of the 2xxx series, comprising the following alloying elements: - Cu, in a weight fraction of between 3% and 7%; - Mg, in a weight fraction of between 0.1% and 0.8%; - at least one element, or at least two elements or even at least three elements chosen from: • Mn, in a weight fraction of between 0.1% and 2%, preferably of at most 1% and in a preferred manner of at most 0.8%; • Ti, in a weight fraction of between 0.01% and 2%, preferably of at most 1% and in a preferred manner of at most 0.3%; • V, in a weight fraction of between 0.05% and 2%, preferably of at most 1% and in the preferred manner of at most 0.3%; • Zr, in a weight fraction of between 0.05% and 2%, preferably of at most 1% and in a preferred manner of at most 0.3%; • Cr, in a weight fraction of between 0.05% and 2%, preferably of at most 1% and in the preferred manner of at most 0.3%; and - optionally at least one element, or at least two elements or even at least three elements chosen from: • Ag, in a weight fraction of between 0.1% and 0.8%; • Li, in a weight fraction of between 0.1% and 2%, preferably 0.5% and 1.5%; • Zn, in a weight fraction of between 0.1% and 0.8%.

ultrasonic inclusion detectors for detecting sulfides, nitrides, silicates, oxides, chemical compounds, and non-metallic particles for use in the measuring and quality-control analysis of liquid metals
The invention relates to a fluid device (1) comprising a housing (2) provided with a channel (3) defined by walls, one of which being a first main wall (10), the channel (3) extending between two openings, a so-called inlet (4A) and a so-called outlet (4B), and an open-pored porous medium in a metal material, a so-called metal foam (30), arranged in the channel (3) between said inlet (4A) and outlet (4B). The metal foam (30) and said first main wall (10) are made of a single component and consist of the same material, and the metal foam (30) has a random spatial distribution of the pores.
