Abstract: The invention relates to a process for manufacturing a part, comprising the formation of successive solid metal layers (201 . . . 20n) that are stacked on one another, each layer describing a pattern defined from a numerical model (M)), each layer being formed by depositing a metal (25), referred to as filling metal, the filling metal being subjected to an input of energy so as to melt and form said layer by solidifying, in which process the filling metal is provided in the form of a powder (25), the exposure of which to an energy beam (32) results in melting followed by solidification such that a solid layer (201 . . . 20n) is formed, the process being characterized in that the filling metal (25) is an aluminum alloy comprising at least the following alloying elements: −2 to 10% by weight of Cr; −0 to 5% by weight, preferably 0.5 to 5% by weight, of Zr. 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 properties, while obtaining a process that has an advantageous output.

Abstract: When welding with a consumable wire electrode, current contacting occurs when the electrode wire passes by a readily electrically conductive contact element. In order to improve the current contacting and reduce the wear of the contact element in particular, the invention proposes subjecting contact elements to a cold treatment prior to using same. The cold treatment has a cooling phase during which the temperature of the contact element is reduced to a lower target temperature, a subsequent holding phase in which the contact element is substantially held at the target temperature, and a final heating phase, in which the contact element is brought to an upper target temperature. The use of contact elements treated using the method according to the invention leads to a substantial increase of the wear resistance compared to untreated contact elements.

Abstract: A formation of multielement nanoparticles is disclosed that includes at least three elements. Each of the at least three elements is uniformly distributed within the multielement nanoparticles forming nanoparticles having a homogeneous mixing structure. At least five elements may form a high-entropy nanoparticle structure. A method for manufacturing a formation of multielement nanoparticles includes providing a precursor material composed of the at least three component elements in multielement nanoparticles; heating the precursor material to a temperature and a time; and quenching the precursor to a temperature at a cooling rate to result in a formation of multielement nanoparticles containing at least three elements and the heating and the quenching representing a multielement nanoparticle thermal shock formation process. A corresponding system for manufacturing the formation of multielement nanoparticles and a method of using the multielement nanoparticles are also disclosed.
