The amorphous Fe67.5Ni1Al5Ga2P9.65C6.75B4.6Si3Sn0.5alloy was pretreated at different temperatures.Structural and thermodynamic analysis of the amorphous alloy were conducted by XRD（X-ray diffraction）and DSC.The analysis reveals that the atoms in the alloy are diffused each other then interacted among dissimilar atoms to form clusters or atomic colony by pre-annealing at a lower temperature.After pretreatment

the grain size in the amorphous alloy with partial crystallization is decreased

and the precipitation phase distribution is also more uniform.Meanwhile

crystallization treatment area is increased with more crystallization phase types.As a result

the internal structure and status of amorphous alloys become change.At a certain range

with the increase of pre-annealing temperature

crystallization area of amorphous alloy is increased with a higher crystal growth rate.
