Abstract

Die Erfindung betrifft Legierungen auf der Basis von, insbesondere unter Verwendung von schmelz- oder pulvermetallurgischen Verfahren hergestellten, Titanaluminiden, vorzugsweise auf Basis von y (TiAl), wobei TiAl-Legierungen mit weiteren Zusätzen Volumenanteile der β-Phase enthalten. Die Legierungen zeichnen sich aus durch Komposit-Lamellen-Strukturen mit B19-Phase und β-Phase in jeder Lamelle, wobei das Verhältnis, insbesondere das Volumenverhältnis, der B19-Phase und β-Phase jeweils in einer Lamelle zwischen 0.05 und 20, insbesondere zwischen 0.1 und 10, beträgt.The invention relates to alloys based on, in particular using melt or powder metallurgy produced titanium aluminides, preferably based on y (TiAl), wherein TiAl alloys containing further additives volume fractions of the β-phase. The alloys are characterized by composite lamellar structures with B19 phase and β-phase in each lamella, wherein the ratio, in particular the volume ratio, the B19 phase and β-phase in each case in a lamella between 0.05 and 20, in particular between 0.1 and 10, is.

Die Legierungen zeichnen sich durch hohe Festigkeit und Kriechbeständigkeit bei gleichzeitig hoher Duktilität und Bruchzähigkeit aus.The alloys are characterized by high strength and creep resistance combined with high ductility and fracture toughness.
