Abstract : The results of experimental investigations to evaluate the cantilever fatigue propertzes of Nb + 1 wt.-% Zr are presented in this report. Tests were conducted with specimens in 800 F liquid potassium and in 1600 F liquid lithium to determine what effect, if any, these alkali metals would have on the fatigue properties of this alloy. The tests resulted in no serious contamination of the test material, and endurance limits for the test conditions were established. (Author)
