Abstract
Transmission electron microscopy is used to resolve the crystallization of the bulk amorphous alloy (Fe40Ni40P14B6)96Ga4. Nanocrystallization is observed in supercooled liquid region for bulk amorphous alloy (Fe40Ni40P14B6)96Ga4. The annealing temperature varies from 680Â K to 730Â K where supercooled liquid region exists. The annealing time is 60Â min for all samples. Crystallization does not occur until the annealing temperature exceeds 680Â K. Crystal unions consisting of nanocrystals start to precipitate in amorphous base when the annealing temperature arrives at 690Â K. The average diameter of crystal unions is about 150-250Â nm. Crystal unions already knock together when the annealing temperature comes to 700Â K. When the annealing temperature reaches 710Â K, another microstructure is formed, consisting of the uniform nanocrystals with a grain size of about 8Â nm. When the annealing temperature is increased to 730Â K, the nanocrystals grow up into the bacilliform crystals with the average diameter of about 30Â nm.
