Available in PDF, EPUB and Kindle. Book excerpt: Progress reported includes the selection of 15 ternary bases for further study in steam or water. About 75 compositions were prepared and are being arc- melted for fabrication into corrosion specimens. Investigations of Zr purity and heat treatment effects on corrosion are being continued. Included are data from corrosion tests on binary alloys with superheated water and steam, and a list of alloys for initial investigation based on results of corrosion screening tests. (J.H.D.).

Available in PDF, EPUB and Kindle. Book excerpt: Corrosion data for zirconium alloys exposed to 680 deg F water for 336 hr are presented. For this exposure time, all specimens exhibited the desirable tenacious, black oxide coating. Preliminary studies were made of the transformation kinetics of Zr-30 Nb, Zr-30 Nb-1 Mo, and Zr30 Nb-3 Mo alloys. Hot rolling these ingots at 1550 deg F resulted in severe edge cracking and excessive air contamination. Nevertheless, small specimens were betaquenched from 1000 deg C and isothermally transformed at 680 and 750 deg F. Hardness versus transformation time curves did not show the relatively sharp hardness increase which signifies the beginning of beta transformation. Corrosion specimens are being prepared for investigation of the effect of zirconium purity on corrosion resistance. (M.C.G.).

Available in PDF, EPUB and Kindle. Book excerpt: Corrosion testing data are presented for a large number of Zr alloys in 68O deg F water (1043 and 1902 hr), 750 deg F steam (329 hr), and 900 deg F steam (97 hr). These alloys include Zircaloy-2 and Zr alloyed with Nb, Sn, V, Sb, C r, Cu, Fe, Si, W, Mo, Ta, Co, Pt, Pd, Rh, As, Bi, Te, Ge, Ag, and Ni. Tensile test data are also reported for ten of these alloys at 68O deg F; these alloys are Zr alloyed with Nb, Sn, Fe, V, Cr, Mo, Sb, and Co, in addition to unalloyed Zr and Zircaloy-2. (D.L.C.).

Available in PDF, EPUB and Kindle. Book excerpt: Specimens which previously showed promising corrosion resistance in 750 deg F steam sfter 329 hr exposure were reentered in test for an additional 480 hr. Additional tin alloys were included. The compositions Zr--0.5 Nb, Zr-IV, and Zr-- 1 Sb and the alloys Zr--Fe, Zr--Cr, and Zr--Mo appeared the most promising. The corrosion resistance of Zr--Sn alloys was not sufficient to consider the alloy for further development. (M.C.G.).

Available in PDF, EPUB and Kindle. Book excerpt: The development of zirconium-base alloys possessing exceptionally good corrosion resistance to 680 deg F water or 750 to 900 deg F steam and/or improved strength at elevated temperatures is discussed. Approximately 100 binary compositions were prepared and screened by corrosion testing in 680 deg F water; selected compositions were exposed to 750 deg F steam. The data obtained indicated promising bases for ternary and quaternary alloys. Related investigations involving zirconium purity and heat treatment for improvement of corrosion properties are proceeding. Hydrogen pickup and mechanical properties will be used as acceptability tests on promising compositions. (auth).

Book excerpt: Corrosion and hydrogen pickup data are available on ternary alloys in 680 deg F water for an exposure time of 4800 hr. 1n general, the longer the time to transition, the lower the post-transition corrosion rate was. Ternary zirconium alloys were exposed to 750 deg F steam for a period of 3000 hr. Weight gain and hydrogen pickup values were.

Available in PDF, EPUB and Kindle. Book excerpt: 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).
