An Investigation of the Chromium-Nickel-Niobium Ternary System

Abstract

An effort was made to plot the boundaries of the phase zones of the ternary system Cr-Ni- nb, limited to that portion of the concentration triangle between a line for the binary Cr-Ni alloys and a line connecting the intermetallic compounds NbCr2 and Ni3 nb. Each of the ternary systems (Cr-Ni- Ni3Nb and Cr-NbCr2-Ni3Nb) have a phase equilibrium diagram which, at 1100 C, contains intervals of single, double, and triple-phase equilibria. A eutectoid transformation is apparently lacking in the Cr-Ni system. An anomalous variation in volume occurs when certain alloys of the Cr-Ni system quenched from 1310 deg C are tempered. The boundaries of the phase intervals in an isothermal cross section of the phase diagram of the Cr-Ni-Nb s stem were plotted for 1100 deg C.
