<p>The invention relates to a method for casting objects from a ??-titanium alloy containing titanium molybdenum with a molybdenum content of 7.5 to 25 %. According to the invention: a melting of the alloy is carried out at a temperature of higher than 1770 degree C; the molten alloy is precision cast into a mold corresponding to the object to be produced, and this cast object is subjected to a hot-isostatic pressing, solution annealing and subsequent quenching. An efficient production of objects made from ??-titanium alloys in the precision casting process is achieved using the inventive method. The invention thus creates the possibility of combining the advantageous properties of ??-titanium alloys, particularly their excellent mechanical properties, with the advantages of a production of objects in the precision casting process. Even objects having complex shapes, which could not or could not be sensibly produced by conventional forging methods, can be produced from a ??-titanium alloy thanks to the invention.</p> |
