Abstract

Die Erfindung bezieht sich auf eine Turbinenschaufel oder Verdichterschaufel, welche durch spanabhebende Bearbeitung aus einem Vormaterial erstellt ist.
Erfindungsgemäß ist vorgesehen, die Schaufel mit den Werkstoffeigenschaften bei Raumtemperatur:
  • Zugefestigkeit: Rm = mindestens 700 N/mm2
  • Dehngrenze: Rp0,2 = mindestens 550 N/mm2
  • Dehnung: A = mindestens 15%
  • Einschnürung: Z = mindestens 10%
    • für Dampfturbinen oder Gasturbinen sowie Verdichter, gebildet aus einem pulvermetallurgisch (PM), bei Pulverisierung einer Schmelze durch Gasverdüsung mittels Stickstoffes und heißisostatischen Pressens (HIP) des Pulvers, hergestellten, gegebenenfalls unverformten Vormaterial, welches spanabhebend bearbeitet und die derart erstellte Turbinenschaufel thermisch behandelt oder vergütet ist.
