METHOD FOR MANUFACTURING A PART FROM ALUMINIUM ALLOY, THE ALLOY COMPRISING AT LEAST ZIRCONIUM AND MAGNESIUM

An object of the invention is a method for manufacturing a part 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, 35), the filler metal being subjected to an energy supply so as to melt...

Beschreibung
Zusammenfassung:	An object of the invention is a method for manufacturing a part 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, 35), the filler metal being subjected to an energy supply so as to melt and constitute, when solidifying, said layer, the method being characterized in that the filler metal (15, 35) is an aluminum alloy including the following alloy elements, in weight percents:Mg: 0%-6%;Zr: 0.7%-2.5%, preferably according to a first variant >1% and ≤2.5%; or preferably according to a second variant 0.7-2%; and possibly 0.7-1.6%; and possibly 0.7-1.4%; and possibly 0.8-1.4%; and possibly 0.8-1.2%;at least one alloy element selected from Fe, Cu, Mn, Ni and/or La: at least 0.1%, preferably at least 0.25%, more preferably at least 0.5% per element;impurities:
