Microstructural changes in Nb-20, 30, 40, 50 and 60 at%Zr alloys aged at 673∼973 K were mainly observed by means of transmission electron microscopy, and five time-temperature-transformation (TTT) diagrams of each composition and a coherent binodal line was obtained experimentally. The results obtained are as follows: (1) Sequences of the phase transformation in this alloy system are divided into four types. (2) An area of the coherent phase decomposition of the β phase is asymmetric and is located at about 400 K lower temperature than that of the chemical phase decomposition, which shows a strong elastic constraint on the phase decomposition in this alloy system. (3) The area of the coherent phase decomposition predicted based on the system free energy theory agrees well with the experimental one.
