Abstract

The crystallization behaviour of Fe–B metallic glasses is discussed in terms of nucleation theory, taking account of the change in concentration during crystallization. The start, course, and end of crystallization of α-Fe and Fe₃B phases are described as functions of time and temperature. The calculated results are compared with calorimetric and X-ray measurements and the differences are discussed. In addition, the thermodynamic parameters, melting temperature, heat of fusion, and heat of crystallization, are measured.
