| Research Abstract |
In this study, the abnormal temperature dependence of shape memory behavior was investigated from the view point of interstitial impurities by in situ x-ray diffraction measurements and in situ transmission electron microscope observation. As a result, the origin of the abnormal temperature dependence of shape memory behavior was nano-sized (about 3nm) lattice modulation structure (nanodomains) which was introduced by interstitial impurities.
