The role of X on the properties of FeXBSi metallic glasses

Abstract

The kinetics of crystallization processes in a series of metallic glasses, Fe 78X 2B 16Si 4, with X as one of the elements of groups IV–VIII in the periodic table, have been studied using differential scanning calorimetry, and the behaviors of the kinetic parameters are described. A novel method of analysis, suggested by the kinetic equations, entails partitioning the total heat of crystallization into separable heats of crystallization of the constituent phases. This technique has been used to show that the various additive elements X may be classified into groups according to the affinity of X for the elements in the parent FeBSi ternary metallic glass.
