Corrosion data for zirconium alloys exposed to 680 deg F water for 336 hr are presented. For this exposure time, all specimens exhibited the desirable tenacious, black oxide coating. Preliminary studies were made of the transformation kinetics of Zr-30 Nb, Zr-30 Nb-1 Mo, and Zr30 Nb-3 Mo alloys. Hot rolling these ingots at 1550 deg F resulted in severe edge cracking and excessive air contamination. Nevertheless, small specimens were betaquenched from 1000 deg C and isothermally transformed at 680 and 750 deg F. Hardness versus transformation time curves did not show the relatively sharp hardness increase which signifies the beginning of beta transformation. Corrosion specimens are being prepared for investigation of the effect of zirconium purity on corrosion resistance. (M.C.G.)
