Ein als Schaufelblatt 2 ausgeführter Gusskörper wird mit seinem einen Ende durch die Öffnung 5 in die Presskanne 4 geführt. Die vorzugsweise aus Stahl bestehende Presskanne 4 wird im Bereich der Öffnung 5 gasdicht an den Gusskörper angelötet oder angeschweisst. Durch eine nicht dargestellte weitere Öffnung der Presskanne 4 wird ein den Schaufelfuss der Turbinenschaufel 1 aufnehmender Hohlraum der Presskanne mit Legierungspulver aufgefüllt. Die Presskanne 4 wird sodann evakuiert und gasdicht verschlossen.
Die das Schaufelblatt 2 bildende Legierung weist bei Raumtemperatur eine Duktilität von ca. 0,5 bis 1% , die den Schaufelfuss 3 bildende Legierung hingegen eine solche von 18 bis 20 % auf. Bei einer Temperatur von ca. 700°C besitzt das Schaufelblatt 2 eine Kriechfestigkeit, welche erheblich über der Kriechfestigkeit der üblicherweise in diesem Temperaturbereich verwendeten Nickelbasis-Superlegierungen liegt. Die Turbinenschaufel 1 zeigt eine dem Werkstoff des Schaufelblattes 2 entsprechende Duktilität von 0.5 bis 1% auf, was bedeutet, dass durch die Grenzschicht 6 die Duktilität der Schaufel nicht negativ beeinflusst wird. Die Turbinenschaufel 1 nach der Erfindung zeichnet sich demnach durch einen Schaufelfuss 3 mit hoher Duktilität und ein bei Raumtemperatur zwar sprödes, bei hohen Temperaturen jedoch eine grosse Kriechfestigkeit aufweisendes Schaufelblatt 2 aus. Die Festigkeit der Grenzschicht 6 reicht aus, um einen sicheren Betrieb der Turbinenschaufel 1 bei hohen Temperaturen zu gewährleisten.
