NiTiNb is a ternary nickel-titanium-niobium shape memory alloy engineered to exhibit wide thermal hysteresis, enabling large temperature differentials between the martensite and austenite phases during thermomechanical cycling. This composition is used in applications requiring high actuation temperatures, damping over broad temperature ranges, or robust recovery behavior under cyclic loading, particularly in aerospace sealing systems, precision actuators, and vibration isolation devices where conventional NiTi alloys lack sufficient thermal span or functional stability.
