An improvement of the thermodynamic description of the ternary Fe–Si–B system by means of Calphad method has been carried out in this work considering not only the equilibria involving the stable Fe2B phase but also the metastable ternary equilibria in which the Fe3B phase occurs. Furthermore, the glass transition is introduced in the Calphad framework as a second-order one using the tools provided by the Hillert–Jarl formalism of the ferromagnetic transitions not yet applied to Fe–B and Fe–Si–B. The assessments have been made using data available in the literature regarding both the amorphous and crystalline phases. The results improve the previous ones for the glassy phase while keeping the agreement with experimental data concerning stable equilibria.

Abstract

An improvement of the thermodynamic description of the ternary Fe–Si–B system by means of Calphad method has been carried out in this work considering not only the equilibria involving the stable Fe2B phase but also the metastable ternary equilibria in which the Fe3B phase occurs. Furthermore, the glass transition is introduced in the Calphad framework as a second-order one using the tools provided by the Hillert–Jarl formalism of the ferromagnetic transitions not yet applied to Fe–B and Fe–Si–B. The assessments have been made using data available in the literature regarding both the amorphous and crystalline phases. The results improve the previous ones for the glassy phase while keeping the agreement with experimental data concerning stable equilibria.
