Outline of Final Research Achievements

This study has been devoted to develop the short-time and non-destructive evaluation technique concerning glass material based on Raman scattering: Relation of the short-to-middle range order structure, which is obtained from the Raman spectrum and Boson peak, of glass to its mechanical/elastic property has been clarified, and consequently significant insights into the local processability and structural relaxation have been successfully obtained.
