N2 - In situ measurement of boson peak in several glasses was performed during the crystallization process to elucidate crystallization dynamics. In this study, it was experimentally illustrated that a drastic decrease in elasticity and damping of the boson peak occurred during the crystallization process when T/ Tg ∼1.1-1.2. A possible mechanism for the crystallization precursive stage is also discussed, which integrates our boson peak observation results, Hikima's description [J. Mol. Struct. 479, 245 (1999)], Cabral's thermodynamic data [J. Non-Cryst. Solids 343, 85 (2004)], and other works.
