In the metallic glass material, as the solid metallic glass is heated and heated (solid metallic glass → supercooled liquid (K) exhibiting a viscous flow state → crystal → molten liquid metal)
And change. Conversely, when cooling molten liquid metal to metallic glass, as long as a sufficient cooling rate is satisfied,
(Molten liquid metal → supercooled liquid exhibiting viscous flow state
(K) ⇒ solid metallic glass) and not (crystal).

On the other hand, in the conventional amorphous raw material, when the temperature of the solid amorphous material is increased by heating, the temperature changes from solid amorphous to crystalline to molten liquid metal as the temperature is increased.
