摘要: Nucleation and growth rates of the MSI metastable phase crystals amorphous alloy Fe32Ni36Cr14P12B6 have been studied in detail using quantitative transmission electron microscopy. Three different types activation energies are involved crystallization:En for nucleation,Eg crystals, andEc whole process crystallization. All three were determined experimentally:En andEg present paper a former work. A general formula was developed which combines found to be good agreement with experimental values. Furthermore, attention has drawn value Avrami exponent is very detailed theory 1955 by Ilschner, differing common literature Also, diffusivity metalloid this reported rate crystals.
