    The phase transformation behaviors and shape memory characteristics of Ti-(46-x)Ni-3.0Cu-xMo(x=0.3, 0.5, 0.7, 1.0 at.%), Ti-(45.5-x)Ni-3.0Cu-xMo(x=0.3, 0.5, 0.7, 1.0 at.%), (50+x)Ti-(46.5-x) Ni-3.0Cu-0.5Mo(x=0.3, 0.7 at.%) and Ti-(45-x)Ni-5Cu-xFe(x=1.0, 1.5, 2.0, 2.5 at.%) alloys were studied by differential scanning calorimitery, electrical resistivity measurement, X-ray diffraction, constant load thermal cycling test and tensile test. As increased Mo-content in Ti-Ni-Cu-Mo alloys, stability of the R phase and the B19 phase increased. Ti addition to Ti-Ni-Cu-Mo alloys decreased stability of the R phase and the B19 phase decreased, while transformation temperature increased. Ti-(46.0-x)Ni-3Cu-x(0.7, 1.0 at.%) alloys showed three-stage transformation behaviors, i.e., B2-R-B19-B19'. As increased Fe-content in Ti-Ni-Cu-Fe alloys, stability of the R phase and the B19 phase increased, while transformation temperature increased. Ti-(45-x)Ni-5Cu-xFe(x=2.0, 2.5 at.%) alloys showed three-stage transformation behaviors, i.e., B2-R-B19-B19'. In Ti-Ni-Cu-Mo and Ti-Ni-Cu-Fe alloys, showed the excellence shape memory effect in constant load thermal cycling test, as increased Mo-content and Fe-content. In results of tensile test, superelastic behavior observed extensive range as compared with Ti-Ni-5Cu alloy.
