The effects of composition, phase, morphology, and heat treatment on creep and tensile properties and on corrosion in high-temperature water and steam were evaluated for three zirconium ternary systems. Dilute alloys, containing less than 1 at. pct total solute, exhibited corrosion resistance equal to or better than that of Zircaloy-2 but had inferior mechanical properties. Mechanical properties were significantly improved by adding 3 to 7 at. pct solutes; however, the added solute caused a decrease in corrosion resistance. The Zr-Sn-Cb system showed the best combination of creep and corrosion behavior. Zr-Sn-Cr and Zr-Cb-Cr alloys generally were much less corrosionresistant than Zr- Sn- Cb alloys but could be heat-treated to high strength with considerable improvement in creep resistance. (auth)
