Ni-basierte Superlegierung

Legierungen: Aufbau, Eigenschaften und Anwendung

Ni-basierte Superlegierung

Ni-basierte Superlegierung bezeichnet eine Nickelgrundlegierung mit optimierter γ/γ'-Mikrostruktur für Hochtemperatureinsatz. Durch gezielte Legierung (z.B. Al, Ti, Cr, Co, Re) und kontrollierte Ausscheidungshärtung wird hohe Kriechfestigkeit, Ermüdungsbeständigkeit und Oxidationsresistenz erreicht. Solche Legierungen werden als gegossene, richtkristallisierte oder einkristalline Turbinenwerkstoffe eingesetzt, wobei Mikrostrukturstabilität über lange Zeiten entscheidend ist.
