IMPROVED ZIRCONIUM ALLOYS. Technical Progress Report, February 1 1961- February 28, 1961
The development of zirconium-base alloys possessing exceptionally good corrosion resistance to 680 deg F water or 750 deg --900 deg F steam and/or improved strength at elevated temperatures with corrosion resistance equivalent to Zircaloy-2 was investigated. Approximately 100 binary compositions were screened by corrosion testing in 680 deg F water and 750 deg F steam; selected compositions were exposed to 900 deg F steam. Data obtained indicated a number of highly promising bases for ternary alloy studies in superheated water or steam. On the basis of 2000-hour tests, alloys were obtained which initially satisfy the objectives for 680 deg F water. The compositions are based on Zr-Nb, Zr-Sn, and Zr-Sb with ternary additions of Te, Ge, or Nb. Initial data for exposure to 750 deg and 900 deg F steam indicate very promising corrosion behavior of some ternary alloys. (auth)
