Abstract

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 Ni 4 Ti 3 but decreased amount of Ni 3 Ti from lower to upper region leads to obviously decreasing transformation temperature, increasing hardness and tensile strength but reduced ductility.
