| Abstract Scope |
The initial stage of crystallization in a metallic glass, when heated up to the glass transition temperature, often involves in nucleation and growth of a nanoscale, metastable crystalline phase. This phase is then consumed in the subsequent stage to facilitate the formation of thermodynamically stable phases. This type of sequential crystallization, in a variety of families of bulk metallic glasses, has been investigated by in situ synchrotron x-ray and neutron diffraction in the present study. The crystallization pathways and kinetics will be presented in detail and the implication for the glass-forming ability will be discussed. The results may help to better understand phase-transformation kinetics in materials far from equilibrium. |
