Comparative study of non-isothermal crystallization kinetics between Fe80P13C7 bulk metallic glass and melt-spun glassy ribbon

► Comparative study on the crystallization kinetics between Fe80P13C7 bulk and ribbon amorphous samples was performed. ► The larger apparent activation energy shows less amount of free volume in the supercooled liquid state in bulk sample. ► The less local Avrami exponent shows higher degree of short-range order in the supercooled liquid state in bulk sample. ► It shows that the supercooled liquid state of metallic glasses is not fully relaxed state. ► The supercooled liquid state of metallic glasses is related to its initial state.
