Abstract:

In-situ diffraction investigations of superelastic NiTi shape memory alloys with neutron and synchrotron x-ray radiation were used to examine the evolution of the phase state of the material as a function of stress and strain, respectively. The results suggest that the transition from austenite to martensite is not complete even at the end of the superelastic plateau, and that significant load transfer to residual austenite takes place.
