Ti-13Nb-13Zr alloy was produced by arc melting, solution treated at 1000°C/1h followed by water quenching, cold forged and annealed at 1000°C/1h or 900°C/30min followed by water quenching. Mechanical properties of this alloy were evaluated by tension tests at room temperature. The elastic region of the stress-strain curve was analyses according to the modified equation of Ramberg-Osgood, which degree of non-linearity is associated to parameter n. It was observed that aging treatment at 400°C/3h, after the annealing, decreases the differences between mechanical properties; moreover, the linearity of elastic region improves.
