| Outline of Final Research Achievements |
The strength of LPSO phase with kink bands introduced by plastic deformation showed twice as high as initial state. The relationship between the kink band density and strength is experimentally quantified in a temperature range from room temperature to 573K, obtaining significant results leading to the derivation of quantitative guidelines for the strengthening by kink bands. Meso-scale structural analysis such as orientation and morphology of kink bands advances, also with its geometric features, aspects of the high-speed development of the lens-shaped kink boundary by in-situ observations were captured. The large contribution of basal sliding was showed by measurement of shear strain of kink vicinity quantified by nanoscale marker. These strongly suggest the interpretation by the disclination model of kink. In addition, the origin of large flow stress of LPSO structure was clarified by the establishment of identification of high-temperature deformation mechanism.
