Research on the phase equilibria of the Nb-- Zr alloy system is reported as a function of composition and temperature. The invariant transformation temperathre level of the monotectoid reaction was found at 615 deg C. An investigation was begun on the transformation kinetics of niobiumbase zirconium alloys for quenching from the beta-niobium region to isothermul temperature levels below the monotectoid reaction temperature or the niobium solvus bound- ary. The initial efforts were directed toward developing a suitable technique for fabricating test specimens. A 90 wt.% Nb alloy was chosen for preliminary investigation because this composition is near the solvus boundary. Results of preliminary testing are included. (B.O.G.)
