Abstract
Die Erfindung betrifft kaltumformbare Formkörper aus Titanbasislegierungen. Der Erfindung liegt die Aufgabe zugrunde, Formkörper auf Titanbasis zu entwickeln, die eine hohe Plastizität und Verformbarkeit bei Raumtemperatur besitzen und die hochfest, korrosionsbeständig und biokompatibel sind. Diese Aufgabe wird mit Titanbasislegierungen gelöst, die in ihrer Zusammensetzung der Formel xTi-y (Nb+Ta) -zM entsprechen, worin x = 100-(y+z) Gew.-%, y = 10 bis 50 Gew.-%, z = 1 bis 10 Gew.-%, und M mindestens ein Element aus der mit den Elementen Cr, In, Zr, Ag, Au und Pd gebildeten Gruppe ist, und die ein Gefüge des β-Legierungstyps mit einer definierten homogenen Mikrostruktur besitzen, welches zu mindestens 92 Volumen-% aus duktilen Dendriten besteht. Zur Herstellung dieser Formkörper wird eine Schmelze dieser Legierung unter Raschabkühlungsbedingungen mit einer Abkühlrate im Bereich von 100 bis 1000 K/s abgekühlt. Die Formkörper sind als Implantate im medizinischen Bereich, aber auch in der Flugzeugindustrie, der Raumfahrt, der Fahrzeugindustrie, der chemischen Industrie, im allgemeinen Maschinenbau und als Sportgeräte anwendbar.
