Process for producing an implant from a titanium alloy, and corresponding implant

Abstract

A process for producing a medical implant from a titanium alloy, by investment-casting a β-titanium alloy in a casting mold which corresponds to the implant that is to be produced, hot isostatic pressing, solution annealing, and then quenching. The corresponding medical implant is produced from the titanium alloy using the investment casting process, thus allowing economical production of objects from β-titanium alloys. The β-titanium alloy and has a mean grain size of at least 0.3 mm. It is possible to combine the advantageous properties of β-titanium alloys, in particular their excellent mechanical properties, with the advantages of producing objects by the precision casting process, thus enabling even implants of complex shapes, such as femur parts of hip joint prostheses, which have heretofore been impossible (economically) to produce by conventional forging processes, to be produced from a β-titanium alloy.
