A cold NiTiTa alloy was found to be very brittle in the fully annealed condition due to its high-austenite stability, which suppressed stress-induced-martensite transformation and dislocation slip. However, ductility and super-elasticity are largely improved by formation of Ti3Ni4 and Ti2Ni3 precipitates upon aging at lower temperatures. Cold work promotes Ti2Ni3 precipitation during aging. Compared to the as-drawn material, the fully annealed material shows higher strain recovery and elongation after aging for a short amount of time.
