| Outline of Final Research Achievements |
The thermoelastic martensitic transformation is fundamental process of shape memory effect and superelasticity which are applied to from commodities such as eye glass frame to minimally invasive medical devices such as stent. In the present study, formation dynamics and three dimensional structure of thermoelastic martensitic phase have been investigated as listed below. 1) Formation process of nucleation and invariant plane of thermally induced martensite. 2) Microstructure analysis of isothermal martensite. 3) Three dimensional analysis and control of self-accommodation structure. 4) Analysis and control of lattice defects induced by appearance and disappearance of self-accommodation morphology. The expected results have been almost provided in each of subjects.
