Metallic glasses are metastable systems that show relaxation behavior towards a local energy minimum and crystallize when heated sufficiently above their glass transition temperature (Tg). Different modes of relaxation can be accessed by varying the combination of relaxation time and temperature. At temperatures significantly lower than Tg only β-relaxation is expected, corresponding to local rearrangements of few atoms. For temperatures close to Tg and for long times only α-relaxation is observed which corresponds to collective rearrangements in the glass. While these two relaxations are often considered independent, a growing body of evidence shows that they are linked [J. Phys. Chem. Lett., 3 (2012), 735; Intermetallics, 93 (2018), 101]. Additionally few attempts have been made to understand how structural changes during relaxation influence crystallization behavior.
Vit106a as a model system of bulk metallic glasses has been investigated concerning the relaxation dynamics and changes in crystallization behavior using conventional scanning calorimetry correlated to strutural analyses using transmission electron microscopy-based methods.
