Abstract

International. This e-offprint isExperimental Study of the Sb-Sn-Zn Alloy System ONDREJ ZOBAC, JIRI SOPOUSEK, JIRI BURSIK, ADELA ZEMANOVA, and PAVLA ROUPCOVA The Sb-Sn-Zn alloy was prepared and researched by experimental methods, which allow obtaining information on the thermodynamic stability of the coexisting phases. Thermal analysis was used to determine the phase transition temperatures of experimental alloys. Equilibrium composition of coexisting phases after long-term temperature equilibration was determined by electron microscopy. The existence of one ternary stoichiometric phase Sb 2 SnZn was experimentally confirmed by diffraction technique. The CALPHAD method for prediction of the phase diagram of the Sb-Sn-Zn system from binary subsystems was used in this work.

Experimental Determination of Phase Equilibria in the Sn-Zn-Sb System

“…[7] obtained information on the thermodynamic stability of the coexisting phase by using DTA method at 200, 250 and 350°C. [7] However the phase equilibrium and the microstructure of the Sn-Zn-Sb ternary system at higher temperature are lacking.…”

“…[7] obtained information on the thermodynamic stability of the coexisting phase by using DTA method at 200, 250 and 350°C. [7] However the phase equilibrium and the microstructure of the Sn-Zn-Sb ternary system at higher temperature are lacking. Positioning of the phase fields with mutual solubility of all three components and specification of the stability range of the ternary phase depend on the experimental research of the Sn-Zn-Sb ternary system.…”

“…Positioning of the phase fields with mutual solubility of all three components and specification of the stability range of the ternary phase depend on the experimental research of the Sn-Zn-Sb ternary system. [7] In the present work, the phase equilibrium of the Sn-ZnSb system at 400 and 500°C were experimentally determined by using electron probe microanalyzer (EPMA), x-ray diffraction (XRD) and differential scanning calorimetry (DSC). The obtained results are expected to give a better understanding on microstructures in the Sn-Zn-Sb alloys.…”

Calphad-type assessment of the Sb–Sn–Zn ternary system

“…New experimental results relating to phase equilibria in the SbSn-Zn system have been presented in our previous work [6]. This experimental work [6] was a part of a COST project aimed to the study of properties of systems relevant to lead free solders [2].…”

“…This experimental work [6] was a part of a COST project aimed to the study of properties of systems relevant to lead free solders [2]. The continuation of the study, which is devoted to a CALPHAD-type assessment of the Sb-Sn-Zn ternary system and new DTA measurements, is presented in this paper.…”
