Abstract (en)
[origin: WO2010089516A2] The invention relates to a method for producing a blank for a piece made from a superalloy based on Ni, wherein an alloy is produced and thermal treatments are carried out, characterised in that: said superalloy contains at least 2.5% of the total as Nb and Ta, a thermal treatment is carried out in a number of steps, a first step between 850 and 1,0000C for at least 20 minutes to precipitate the phase d on the grain joints, a second step at a temperature above that of the first step, permitting a partial dissolution of the phase d obtained in the first step, an aging treatment comprising a third step and optionally one or more supplementary steps at a temperature mower than that of the first step and which permit a precipitation of the hardening phases ?' and ?". The invention further relates to a corresponding piece.
