Thermodynamic assessment of the Bi–Sn–Zn System
J. Vizdal; Maria Helena Sousa Soares de Oliveira Braga; A. Kroupa; K. Richter; Delfim Soares; Luís Filipe Malheiros de Freitas Ferreira; J. FerreiraA thermodynamic assessment of the Bi–Sn–Zn ternary system was carried out using the CALPHAD approach along with thermodynamic descriptions from new assessments of the Bi–Sn and Bi–Zn systems. Selected experimental data from the literature and our own work were also used. New sets of optimized thermodynamic parameters were obtained that lead to a very good fit between the calculated and e...
The experimental study of the Bi-Sn, Bi-Zn and Bi-Sn-Zn systems
Maria Helena Sousa Soares de Oliveira Braga; J. Vizdal; A. Kroupa; Delfim Soares; J. Ferreira; Luís Filipe Malheiros de Freitas FerreiraThe binary BiSn was studied by means of SEM (Scanning Electron Microscopy)/EDS (Energy-Dispersive solid state Spectrometry), DTA(Differential Thermal Analysis)/DSC (Differential Scanning Calorimetry) and RT-XRD (Room Temperature X-Ray Diffraction) in order to clarifydiscrepancies concerning the Bi reported solubility in (Sn). It was found that (Sn) dissolves approximately 10 wt% of Bi at the eutectic temperatur...
