Book excerpt: Mechanical properties of the uranium-6 wt percent niobium alloy change with aging time and temperature. In general, the ultimate tensile strength and hardness reach a peak, while elongation becomes a minimum at aging temperatures between 400 and 500°C. The first optical evidence of a second phase was in the 400°C-aged alloy, while complete transformation to a two-phase structure was seen in the 600°C-aged alloy. The maximum-strength conditions correlate with the minimum stress corrosion cracking (SCC) resistance. The maximum SCC resistance is found in the as-quenched and 150, 200, and 600$sup 0$C-aged specimens. The as-quenched and 300°C-aged specimens had the greatest resistance to general corrosion in aqueous chloride solutions; the 600°C-aged specimen had the least resistance. (auth).
