In this study superelasticity and corrosion characteristics of 50Ti-(45-X)Ni5Cu-XMo alloys have been investigated by means of electrical resistivity measurements, X-ray diffraction, tensile tests, polarization tests, and optical microscopy. Substitution of Mo for Ni in a Ti-45Ni-5Cu alloy induces the B2-B19 transformation and the stability of the B19 martensite increases with an increase in Mo content. Superelastic recovery of 50Ti-(45-X)Ni5Cu-XMo alloys increases from 33 to 91% with an increase in Mo-content from 0 to 0.5%. The 50Ti-(45-X)Ni-5Cu-XMo alloys show small stress hysteresis below 100 MPa. The pitting potential of 50Ti-(45-X)Ni-5Cu-XMo alloys also increases with the increase in Mo content.
