Abstract
On Ti-50.3%Ni and Ti-48%Ni-2%Fe (at.%) single crystals of
[001], [111], [139], [123] orientations the influence of
preliminary deformation of martensitic phase and aging (marforming)
on shape memory effect (SME) and superelasticity (SE) has been
investigated. It has been shown that marforming leads to occurrence
of SE, which is absent in initial state.
