Abstract

The thermal cycling stability of martensitic transformation in (Ti₅₄Ni₃₄Cu₁₂)_100-xNb_x (x = 0, 6 and 10 at.%) was investigated. The results show that doping Nb into Ti₅₄Ni₃₄Cu₁₂ enhances the thermal cycling stability of the material. After 400 thermal cycles, the shift of martensitic transformation start temperature of Ti₅₄Ni₃₄Cu₁₂ and (Ti₅₄Ni₃₄Cu₁₂)₉₀Nb₁₀ alloys are 1.5 °C and 0.1 °C, respectively. This improvement can be ascribed to the fact that the proper doping of Nb does not significantly reduce the value of λ₂, whereas improves the other cofactor conditions (CC2 and CC3) and the yield strength.
