Abstract

The free energy composition diagrams for the Zr-Nb alloy system have been computed from the phase diagram employing Rudman's technique of phase diagram analysis. The influence of the clustering tendency in the β phase on the sequence of phase transformations in both Zr-rich and Nb (Cb)-rich alloys has been examined. It has been possible to predict different sequences of phase reactions in different ranges of composition and temperature. The experimentally observed phase reactions as reported earlier have been rationalized by the calculated free energy composition plots.
