In this work, we explore the consequences of strain aging NiTi wires (2.46 mm diameter) at moderate temperatures (100ºC). The changes of the stress-strain behaviour on aged, as compared with non-aged wires, with comparatively ...
External temperature effects on the hysteresis of NiTi wires in dampers for stay-cables

The use of NiTi wires, one of the Shape Memory Alloy (SMA) materials that permits efficient damping in stayed cables
for bridges, requires an appropriate behavior when exposed to the external temperature effects. The ...
Functional fatigue recovery of superelastic cycled NiTi wires based on near 100ºC aging treatments
(2015)

Text en actes de congrés.
Accés obert
Functional fatigue affecting superelastic behaviour of NiTi wires includes an accumulation of residual strain and an uneven decrement of transformation stress on cycling. Although this evolution is observed to diminish ...
