Abstract (en)

[origin: WO2016073218A1] A metal article including an at least partially heat treated metal composition, and a method for treating the metal article are provided. The method for treating the metal article may include heating the metal article to a first holding temperature of about 690°C, and holding the metal article at the first holding temperature for at least about 10 hours. The method may also include cooling the metal article from the first holding temperature to a first cooling temperature of about 65°C or less. The method may further include heating the metal article to a second holding temperature of about 615°C, and holding the metal article at the second holding temperature for at least about 10 hours. The method may also include cooling the metal article from the second holding temperature to a second cooling temperature of about 65°C or less.
