Pa, Os, Ir, Rh, Ru, V, Si, Mn, Sn, Pb, W, Sb, Ge, Al, Ti, Mg, Zn, La, and Ba. Also, Zr-base ternary alloys were prepared using the elements Cu, Ni, Nb, Ta, V, Sn, Sb, and W. The maximum total alloy content of the alloys was five per cent. The Zr used was low-Hf sponge, and the alloys were prepared-by arc melting in an Ar atmosphere. The alloys were tested for scaling resistance at the temperatures 1200, 1500, and 1800 deg F in a multi-specimen furnace for periods up to about 300 hours. Scaling Propensity of the alloys was evaluated on the basis of the weight increase per unit area as compared to that of unalloyed Zr. The binary alloys containing Ni and Cu showed the greatest scaling resistance of all the binary alloys at all temperatures. Ternary alloys showed little or no improvement over the most scaling resistant binary alloys. The number of alloys more resistant than unalloyed Zr was about the same at 1200 and 1500 deg F, but was considerably more at 1800 deg F. In general, there was some change in the order of relative scaling propensity based on the average weight increase per average. unit area per hour at the three temperatures. A logarithmic plot of weight increase versus time for most of the alloys showed a sharp increase in the scaling rate after various periods of time, whereas very few showed a decrease. (auth).

Available in PDF, EPUB and Kindle. Book excerpt: The corrosion rates of low-titanium zirconium alloys increased with titanmum content when exposed to water at 290 deg C or to 1 atm oxygen at 290, 350, 400, and 500 deg C. The scaling rate reached a maxmmum (approximately 3000 at 500 deg C and then decreased with increasing titanium content. Under the same conditions, pure zirconium and tmtanium had much lower weight gains, 10 and 4 mg/ dm/sup 2/ respectively. In oxygen at 500 deg C, the oxidation rate law was initially cubic or parabolic for alloys containing 3.75, 15.0, and 50.0 at.% Ti, and then changed to approximately a linear one. The transition times were 17, 7, and 54 min for the in the rate law and the rise in EMF and resistance appeared to be independent variables. The electrical changes were attributed to changes in defect structure, and the rate law ansitions were attributed to structural channges. The reilts provided an explanation for the maximum oxidation ite at 15 at.% Ti and for the differences in the influence of dditives on the corrosion rates of zirconium and titanium in high temperature water. Thc EMIF of the corrosion cell consisting of STAalloy /oxide! O/sup 2/! was a function of the resistance of the oxide layer. The 3.75 and l5.0 at.% Ti alloys had small EMF's and resistances inittally, but EMF and resistance increased appreciably and rapidly at times after the transition stage. The 50 at.% Ti alloy had a very small EMF which was relatmvely constant while the resistance showed a slight increase with time. (auth).
