Influence of Predeformation Temperature on Recovery Performance of Ni₄₇Ti₄₄Nb₉ Alloy Φ16mm Pipe Joint

Abstract:

Using the method of expanding diameter in low temperature and water bath heating, this paper studied the effect of pre-deformation temperature on shape memory recovery characteristics of Ni₄₇Ti₄₄Nb₉ alloy Φ16 mm pipe joint. The results showed that the transformation hysteresis and the radial recoverable strain were relative stable along with the addition of pre-deformation temperature, which were 122°C±4°C and 7.1%±0.3% respectively. Moreover the radial recovery rate of inner diameter declined smoothly with the addition of pre-deformation temperature. Systems considering the three parameters of transformation hysteresis, recoverable strain and strain recovery rate, it seemed the excellent predeformed temperature for Ni₄₇Ti₄₄Nb₉ alloy Φ16 mm pipe joint was in-65~-70°C.
