| Outline of Final Research Achievements |
To clarify the crystal structure of synchronized LPSO alloys and the structural changes by stress loading or thermal heating, we have been performed this project. It is found that the crystal structure of the 18R LPSO single phase is described the crystal structure proposed by the STEM result in bulk scale sample by neutron diffraction at J-PARC. Also, there exists elastic anisotropy between a-axis and c-axis directions. Further, the kink deformation of 18R LPSO single phase is cooperative phenomena of relaxation of strain with nearly constant duration by rotation with precursor. It is found that crystal structure of the MgAl3Gd4 is well described by OD structure proposed by STEM by synchrotron radiation diffraction at SPring-8. Its features are existing of A6Gd8 cluster with interstitial atom at center position and covalent character of Al atom. Thermal coefficient of 18R LPSO single phase was determined, and it is less than that of pure Mg.
