THE CORROSION RESISTANCE OF Zr-Nb AND Zr-Nb-Sn-ALLOYS IN HIGH-TEMPERATURE WATER AND STEAM. PART II

Technical Report ·
OSTI ID:4833686
The effect of heat treatment, and tin and zirconium purity on the resistance to corrosion and hydrogen pickup of a sponge Zr--2.5 wt% Nb alloy was evaluated. The concentration of niobium in solid solution in alpha zirconium was found to affect the oxidation and hydriding rates, but to a different extent. Ternary addition of tin from 0.5 to 1.5 wt% had an adverse effect on the resistance to corrosion and hydrogen pickup. It was indicated that the impurities inherent in the sponge zirconium had little or no effect on the corrosion and hydriding behavior. (auth)
