Title
Crystal Nucleation Mechanism in Fe40Ni40P14B6 Metallic glass (2)
김성균Seong Gyoon Kim, 나형용Hyung Yong Ra
Abstract
The nucleation rate with temperature and time during crystallization of Fe_(40)Ni_(40) P_(14)B_6 metallic glass investigated in the preceding paper( I ) was discussed quantitatively using the classical homogeneous nucleation theory. The diffusion coefficient, glass-crystal interface energy(σ) and dσ/dT(T : temperature) obtained from the non-steady state homogeneous nucleation theory agree well with the reported values, which means that the nonsteady state homogeneous nucleation occurs during crystallization. We also showed that the glass-crystal interfacial energy in this alloy must decrease with temperature and discussed the exponent n of Johnson-Mehl-Avrami equation.
