Abstract

Differential scanning calorimetry has been used to study the isothermal crystallisation of an Fe80P13C7 metallic glass with additions of Ti and Cr. Between 768 and 781 K the crystallisation occurs in a single stage, the kinetics of which fit an Avrami-Johnson-Mehl relationship with exponent n = 5.1 ± 0.2. The activation energy for the process is 105 ± 5 kcal/mole, which is greater than that for the diffusion of P in glassy Fe---P---C, but less than that calculated for viscous flow. The significance of these values is discussed.
