摘要：
In this paper we discuss the study of phase equilibria in the Ti-Zr-Sn system in the whole range of composition and temperature using own experimental results associated with the evaluated literature data. The solidus and liquidus projections are plotted. An isothermal section at 1000 °C is described. The stability domains of intermetallic phases (binary phases and their extension inside ternary ones) were refined. The shape of the homogeneity range of (Ti,Zr)5Sn3+x at 1400 °C, as well as in the temperature interval 1080-1400 °C was determined. According to the highest thermodynamic stability among all phases of the system, this phase defines the character of phase equilibria in the system, being in equilibrium with most phases, except for Ti2Sn3 and Sn and having the widest region of primary crystallization. A number of isopleths were constructed to determine the extension of the phase regions.
