Abstract

Die Erfindung betrifft ein Verfahren zur Herstellung eines Verbundhalbzeugs aus einer ausscheidungsfähigen Kupferlegierung, bestehend aus zumindest einem Kern- und einem den Kern- umschließenden Mantelbereich ein, ausgeführt durch folgende Schritte:

  • Glühen von Ausgangsmaterial bei hohen Temperaturen in oxidierender Atmosphäre, wodurch zumindest in einem der Bereiche die Legierung oder ein Legierungsbestandteil oxidiert und zumindest ein weiterer Bereich nicht oxidiert wird,
  • Abkühlen und/oder nachträgliche Weiterbehandlung mit Bildung einer Ausscheidungsphase,
  • Entfernen der durch den Glühvorgang entstehenden äußeren Deckschicht,
  • Umformen auf Endmaß.
The invention relates to a method for producing a composite semifinished product from a precipitable copper alloy, comprising at least one core and a core enclosing cladding region, carried out by the following steps:
  • Annealing of starting material at high temperatures in an oxidizing atmosphere, whereby at least in one of the regions the alloy or an alloy constituent is oxidized and at least one further region is not oxidized,
  • Cooling and / or subsequent further treatment with formation of a precipitation phase,
  • Removal of the outer cover layer resulting from the annealing process,
  • Forming to final dimension.

Des Weiteren betrifft die Erfindung die Verwendung des Verbundhalbzeugs.
