摘要：

The creep behavior of the niobium alloy C-103 (Nb-10Hf-1Ti-0. 7Zr) has been studied as a function of stress, temperature, and grain size for test times to 19,000 hr. The proposed exponential relation for tertiary creep strain as a function of time describes well the creep curves. The original purpose for conducting this creep study was to provide design data to facilitate use of C-103 in the heat exchanger and related components of a small, 2-kw, electric, isotope-fueled Brayton cycle space power system.
