“…However, metallic glasses are thermodynamically metastable and will undergo devitrification upon heating, which can destroy those novel properties due to embrittling the metallic glasses [4][5][6]. On the other hand, the metallic glass composites prepared through annealing can be reinforced by the formation of nanocrystalline, leading to apparent improvement of the mechanical, magnetic and some other properties of the materials [7][8][9][10]. Obviously, the thermal stability is a key property to understand the structural transformation during either the solidification or annealing process.…”
