A MATHEMATICAL EXPRESSION OF CRYSTAL GROWTH RATE DURING CRYSTALLIZATION OF AMORPHOUS ALLOYS

A mathematical expression of the crystal growth rate during crystallization of the amorphousalloys was derived from the micromechanism of crystallization newly developed by theauthors. Thus, the satisfactory explanation of the experimental results obtained by Nunogakiet al., Heimendahl et al. and the authors might be found. It seems also to be modelled with theexpression for the crystal growth and the crystal size influenced by time during thecrystallization of amorphous Ni-P alloy foil at in situ heating. Based on the expression, thefactors influencing the crystal growth rate, such as temperature, time and microstructure ofamorphous alloys have been discussed.
