Abstract (en)
[origin: WO2022208037A1] Disclosed is a method for producing a part (20) comprising a formation of successive metal layers (201...20n), said layers being stacked on each other and each being formed by depositing an aluminium alloy (15), the aluminium alloy being subjected to an input of energy so as to become molten and, on solidifying, to form said layer, the method being characterised in that: - during production of the part, prior to the formation of each layer, the aluminium alloy powder is maintained at a temperature no lower than 25°C and below 160°C or between 300°C and 500°C; - the method comprises post-fabrication heat treatment applied to the part at a temperature between 300°C and 400°C; - post-fabrication heat treatment begins with an increase in temperature, the increase being implemented at a rate higher than 5°C per minute; - the method does not comprise dipping in solution followed by hardening.
