Abstract: Analytical expressions are given for the phase boundaries of diagrams of state for $Zr$–$Nb$ and $Zr$–$Sn$ systems. Thermodynamically justified temperature dependences of heat capacity of $Zr$–$1%$ $Nb$, $Zr$–$2.5%$ $Nb$, $Zr$–$1.5%$ $Sn$, and $Zr$–$2.5%$ $Sn$ alloys in two-phase regions are given and recommended for use. The heats of second-order phase transformations $\alpha(Zr) \Longleftrightarrow \beta(Zr)$ in alloys of $Zr$–$Nb$ and $Zr$–$Sn$ binary systems are obtained, and the heats of monotectoid reaction $\alpha(Zr) + \beta(Nb) \Longleftrightarrow \beta(Zr)$ in the $Zr$–$Nb$ system and of peritectoid reaction $\beta(Zr) + Zr_4Sn \Longleftrightarrow \alpha(Zr)$ in the $Zr$–$Sn$ system are calculated.
