Thermal Cycling Influence on the Transformation Characteristics of a Ni50Ti48Nb2 Shape Memory Alloy

Abstract:

The alloy was chosen in order to obtain a shape memory alloy having a wider hysteresis than equiatomic NiTi, that involves a better thermo-mechanical stability. Two samples investigated by differential scanning calorimetry (DSC) were previously annealed at 800oC/12 h and, respectively, 900 °C/12 h followed by furnace cooling. These were afterwards submitted to thermal cycling. The thermal cycling of a Ni50Ti48Nb2 alloy sample previously annealed at 900 °C/12 h results in lower critical points and higher hysteresis values as compared to those of the sample annealed at 800°C/12h, also submitted to thermal cycling. Thus, annealing a metallic part made of such an alloy at 900° C/12 h followed by thermal cycling prior to putting it into service enhances its reliability.

Keywords:
