Abstract:
1. A process for producing a medical implant from a titanium alloy, comprising: providing a β-titanium alloy having a molybdenum content of 12% to 16%, investment-casting the titanium alloy in a casting mold which corresponds in configuration to the implant that is to be produced to produce an implant intermediate, hot isostatic pressing the implant intermediate at a temperature that is less than or equal to a beta-transus temperature of the β-titanium alloy and is not less than 100° C. below the beta-transus temperature, solution annealing the pressed implant intermediate at a temperature range of 700° C. to 900° C., and then quenching the solution annealed implant intermediate to produce the medical implant with a modulus of elasticity in the range of 59.4 kN/mm wherein the investment-casting includes melting the alloy at a temperature of more than 1770° C.
