  • Publication number: 20170241005
    Abstract: Disclosed is process for producing a component of a nickel-based superalloy in which a semifinished part of the component is subjected to a solution heat treatment at a temperature from 1300° C. to 1350° C. and a precipitation heat treatment at a temperature range from 900° C. to 1150° C. The solution heat treatment and/or the precipitation heat treatment are carried out together with further processing of the semifinished part. Also disclosed is a process for treating a component of a nickel-based superalloy after use for some hundreds of hours at a use temperature of more than 500° C. by carrying out a reconditioning heat treatment in the temperature range from 1100° C. to 1280° C.
