摘要：

Ni-rich NiTi alloy was successfully fabricated for the first time using wire arc additive manufacturing (WAAM) technique. The distinct anisotropic microstructure with increased amount of Ni4Ti3 but decreased amount of Ni3Ti from lower to upper region leads to obviously decreasing transformation temperature, increasing hardness and tensile strength but reduced ductility.
