Popis: | 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 → β-Zr and β-(Zr, Nb) → 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 → 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. |
