Abstract
A study was carried out on a Ni-rich NiTi alloy solubilized at 850 °C and subjected to two different treatments: annealing for 0.5 h at 500 °C and rolling at room temperature followed by annealing for 0.5 h at 500 °C. In both cases, measurements of instrumented ultramicrohardness showed that the treatment promoted a superelastic effect.
