In this paper, mechanical and tribological properties of a Ti-50.3 at % Ni alloy were investigated. The transformation temperatures of the alloy were determined using differential scanning calorimetry. Three-point bending tests were performed to characterize the pseudoelasticity and shape memory effects. Uni-axial compression tests were also performed at different testing temperatures. The wear tests were conducted using a pin-on-disk tribometer at testing temperatures ranging from to . The wear results showed that with increasing the testing temperature from to , the wear of the alloy was decreased, which could be attributed to the higher pseudoelasticity of the alloy at a testing temperature of . The pseudoelasticity of the alloy decreased at a higher testing temperature of ; however, its wear resistance increased considerably due to higher ultimate strength and work hardening.
