It was found that surface oxides which developed on zirconium in impure sodium significantly lowered the fatigue life at elevated temperatures. Hydrogen absorption had little effect on the fatigue life at elevated temperatures but lowered the fatigue life at room temperature. Critical recrystallization which occurred above 950 deg F in zirconium (a phenomenon unrelated to the presence of sodium) reduced the fatigue life at elevated as well as low temperatures. The effects attributable to sodium (i.e., the formntion of surface oxide and absorption of reasonable amounts of hydrogen), did not significantly alter the tensile propenties of zirconium at high temperatures.
