PROCESS FOR MANUFACTURING AN ALUMINUM ALLOY PART

A method for manufacturing a part (20) including a formation of successive metallic layers (201 . . . 20n), superimposed on one another, each layer being formed by the deposition of a filler metal (15, 25), the filler metal being subjected to an energy input so as to melt and constitute, when solidi...

Beschreibung
Zusammenfassung:	A method for manufacturing a part (20) including a formation of successive metallic layers (201 . . . 20n), superimposed on one another, each layer being formed by the deposition of a filler metal (15, 25), the filler metal being subjected to an energy input so as to melt and constitute, when solidifying, said layer, the method being characterized in that the filler metal (15, 25) is an aluminum alloy including the following alloy elements (weight %):Ni: >3% and ≤7%;Fe: 0%-4%;optionally Zr: ≤0.5%;optionally Si: ≤0.5%;optionally Cu: ≤1%;optionally Mg: ≤0.5%;other alloy elements:
