摘要：
A method is disclosed for recovering the properties of single crystal and directionally solidified Nickel based superalloys and articles made thereof, after use in a high temperature environment. The method comprises the steps of a stress relief treatment, a γ′ rejuvenation heat treatment at a temperature below the γ′-solvus temperature (Tsolvus, γ′) of the superalloy, a precipitation heat treatment and an aging heat treatment.
