Workability, effects of the heat treatment on the mechanical properties and the microstructures, and the corrosion resistance for pressurized water of Zr- 1% Mo- 1% Cr and Zr- 1% Mo- 1% Ni alloys were investigated in comparison with Zircaloy-2. Percent reductions of the alloys drop-forged in the tempernture range of 800 approximates 900 deg C were nearly the same as those of Zircaloy-2. The alloys were cold rolled by 70% without any intermediate annealing. Remarkable hardening occurred in both alloys when they were quenched from BETA phase. Optimum procedures of the heat treatment to obtain the favorable mechanical properties of Zr-1% Mo-1% Cr and Zr--1% Mo-1% Ni alloys were to temper them at 750 and 600 deg C for 100 min, respectively, after quenching from 950 deg C in BETA phase. The weight gain of Zr- 1% Mo- l% Cr alloy over the corrosion period of 500 hr in pure water at 300 deg C under pressure of 80 kg/cm/sup 2/ was a little bigher than that of Zircaloy-2 but much lower than that of Zr- 1% Mo- 1% Ni alloy.
