High-purity niobium has been tested over the range -196 to 240 deg C. Yield points were observed at all temperatures, the magnitude of the yield drop increasing with decreasing temperature. The temperaturedependence of the yield stress was similar to that of other body-centered cubic metals, and the material was ductile at -196 C. Some experiments on strainaging are reported. The results suggest that oxygen is responsible for the observed repeated yielding and return of yield point on aging. (auth)
