Beschreibung
Zusammenfassung:	The invention describes a process for the production of a composite structural part which can withstand high thermal stress, consisting of at least one graphite part and at least one metal part made of a curable copper alloy. In accordance with the invention, the metal part is bonded, by an HIP process, with the graphite part, which has a layer made of copper or a copper alloy on the bonding surface. In this way, it is possible to use copper-chromium-zirconium alloys with more complex composite structural part constructions and with thin-wall parts of the metal component, without the good mechanical characteristics of the copper-chromium-zirconium alloy being destroyed.
