Abstract
Die Erfindung ermöglicht es, Werkstücke aus Titanlegierungen in einem kostengünstigen Kaltverformungsverfahren zu fertigen. Dies wird erreicht mittels einer (alpha + beta)-Titanlegierung mit etwa 2-4,0 Gew.-% Aluminium, etwa 4-5,5 Gew.-% Vanadium und etwa 4,5-6,0 Gew.-% Molybdän, die durch die zusätzlichen Legierungsanteile von etwa 0,5-1,5 Gew.-% Zirkon und etwa 0,5-1,5 Gew.-% Zinn eine Kaltverformbarkeit bei ausreichender Festigkeit des gefertigten Werkstücks erlangt. Weiterhin wird die Kaltverformbarkeit erfindungsgemäß mittels eines Wärmebehandlungsverfahrens erzielt, mit den Schritten: Glühen der Titanlegierung bei einer unteren Glühtemperatur, welche zwischen 160 DEG bis 230 DEG unterhalb der Umwandlungstemperatur (beta-transus) liegt, und Abkühlen der Titanlegierung auf Umgebungstemperatur. Die Titanlegierung wird vorzugsweise zuvor bei einer oberen Glühtemperatur geglüht, welche 50 DEG und 100 DEG unterhalb der Umwandlungstemperatur (beta-transus) liegt.The invention makes it possible to manufacture workpieces of titanium alloys in a cost-effective cold forming process. This is achieved by using an alpha-beta titanium alloy containing about 2-4.0 wt% aluminum, about 4-5.5 wt% vanadium, and about 4.5-6.0 wt% molybdenum which, due to the additional alloying proportions of about 0.5-1.5% by weight of zirconium and about 0.5-1.5% by weight of tin, achieves cold workability with sufficient strength of the finished workpiece. Furthermore, the cold workability is achieved according to the invention by means of a heat treatment process, comprising the steps of: annealing the titanium alloy at a lower annealing temperature which is between 160 ° and 230 ° below the transition temperature (beta-transus), and cooling the titanium alloy to ambient temperature. The titanium alloy is preferably preliminarily annealed at an upper annealing temperature which is 50 ° and 100 ° below the transition temperature (beta-transus).
