Abstract

Bei einem Verfahren zum Herstellen von homogenen Legierungsmischungen, insbesondere von intermetallischen Phasen, aus mindestens zwei Legierungskomponenten durch Schmelzen von Ausgangsmaterialien in einem induktiv beheizten Kaltwandtiegel, werden die folgenden Verfahrensschritte angewandt:
  • a) in einem ersten Verfahrensschritt werden die Legierungskomponenten zu Blöcken mit vorgewählter mengenmäßiger Legierungszusammensetzung erschmolzen, und
  • b) in einem nachfolgenden Verfahrensschritt wird mindestens einer der Blöcke aus dem ersten Verfahrensschritt in einer induktiv beheizten Kaltwandtieglanordnung (60) aufgeschmolzen, wobei durch die in die Schmelze eingespeiste elektromagnetische Feldenergie die Schmelze derart umgerührt wird, daß deren Legierungskomponenten derart durchmischt werden, daß die Schmelze (55) eine über ihr gesamtes Volumen homogene Materialzusammensetzung erhält.
    • Wahlweise kann der erste Verfahrensschritt in einer induktiv beheizten Kaltwandtiegelanordnung durchgeführt werden, die mit chargierfähigen Ausgangsmaterialien beschickt wird, oder der erste Verfahrensschritt kann durch ein VAR-Verfahren in einer Kaltwandtiegelanordnung durchgeführt werden, die mit vorgeformten Abschmelzelektroden beschickt wird.
