Reference 1 summarized the available information from various AECL* reports describing the aqueous corrosion performance of a zirconium alloy containing 2.5 w/o niobium and 0.5 w/o copper. The reference also presented the results of some studies performed at Bettis with specimens from two Zr-Nb-Cu ingots to verify the AECL work and to gain an insight into corrosion characteristics of the alloy. The above cited work showed that Zr-Nb-Cu alloy possesses excellent corrosion resistance and low hydrogen absorption tendencies when exposed to aqueous media over the temperature range from 680 to 950°F. The work further demonstrated that the corrosion behavior is influenced by prior heat treatment.
