Superelasticity and Corrosion Behavior of 50Ti–(45-X)Ni–5Cu–XMo (at.%) Alloys
Source abstract
Abstract
In this study superelasticity and corrosion characteristics of 50Ti–(45-X)Ni–5Cu–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)Ni– 5Cu–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.
