The creep of niobium in compression between 800 and 1200 un. Concent 85% C is described. The niobium was purified by zone melting, and subsequent contamination was prevented by testing in a vacuum of <10/sup -6/ mm Hg. Above 1000 un. Concent 85% C the creep behavior is complicated by changes in grain size, probably due to recrystallization. The creep strength of the material examined is much lower than that found by other investigators, and the low oxygen content is probably a major reason for the low strength. (auth)
