Outline of Final Research Achievements |
This study aims to clarify formation mechanisms of Synchronized Long-Period Stacking Ordered (LPSO) Structure which features synchronization of chemical and structural modulation and show superior mechanical properties including high strength owing to unique atomic arrangement of LPSO structure, focussing on mainly effects of elastic strain caused by strucural transition. In particular, process of stacking sequence change and relating local strain field as well as segregation of solute elements were examined by high resolution electron microscopy and three dimensional atom probe tomography. Furthermore, computational methods, i.e., both the first principle calculation and phase field simulation, were applied for theoretical analyses of energetics and kinetics in LPSO structure formation.
