Transformation behavior and mechanical properties of a Ti-43.0Ni-5.0Cu-2.0Fe (at.%) alloy

Transformation behavior, shape memory characteristics and superelasticity of a Ti-43.0Ni-5.0Cu-2.0Fe (at.%) alloy were investigated by means of differential scanning calorimetry, X-ray diffraction, thermal cycling tests under constant load and tensile tests. The alloy transformed in three stages i.e., B2-R-B19-B19′. The maximum recoverable elongation of the R-B19 transformation was 2.3%.
