Zusammenfassung:Recommended analytical relations for phase boundaries in the system Zr-Nb, heat capacity of the alloys Zr-1%Nb and Zr-2.5%Nb in two-phase regions α-Zr + β-Zr and β-(Zr, Nb) + liquid are presented. The integral heat of the phase transformations α-Zr [arrow right] β-Zr and β-(Zr, Nb) [arrow right] liquid at constant pressure for the alloys Zr-1%Nb and Zr-2.5%Nb and the heat of monotectoid reaction α-Zr + β-Nb [arrow right] β-Zr are calculated and recommended. Relations are obtained for the heat of the monotectoid reaction as a function of the composition of the alloy.[PUBLICATION ABSTRACT]
