METHOD FOR THE THERMOMECHANICAL TREATMENT OF A TITANIUM ALLOY, AND RESULTING ALLOY AND PROSTHESIS

摘要

The invention relates to a method for the thermomechanical treatment of a titanium alloy comprising between 23 and 27% niobium by atomic proportion, between 0 and 10% zirconium, and between 0 et 1% oxygen, nitrogen and/or silicon, wherein the following steps are carried out: a) an increase in the temperature of the sample of the alloy to a temperature above 900°C; b) a rapid quenching; c) a severe cold deformation; and d) an aging treatment at a temperature between 200 and 600°C, the duration of the treatment being between 10 seconds and 10 minutes. The invention further relates to an alloy obtained by said method and to prostheses produced from such an alloy.
