| Summary: | To tailor the phase transformation behavior of NiTi-based alloys and expand their application potential, this study innovatively employed twin-wire arc additive manufacturing (T-WAAM) technology to fabricate NiTiNb alloys through incorporating Nb as a ternary element. The results demonstrate that the as-deposited alloys exhibit a transformation hysteresis twice as wide as that of NiTi wire, with uniform and stable hysteresis of 49.4°C. This finding confirms the feasibility of using T-WAAM to produce NiTiNb alloys with uniform and wide transformation hysteresis. Furthermore, this research broadens the application of T-WAAM technology in tailoring phase transformation characteristics of ternary NiTi-based components for industrial applications. |
