18 Nov 1977TL;DR: In this paper, a heat treatment is applied to a zirconium-base alloy channel and fuel cladding tubes having unique resistance to accelerated pustular corrosion in the boiling water reactor environment.
Abstract: Zirconium-base alloy channels and fuel cladding tubes having unique resistance to accelerated pustular corrosion in the boiling water reactor environment are produced by a heat treatment causing segregation of intermetallic particulate precipitate phase in two dimensional arrays preferably located along grain boundaries and subgrain boundaries throughout the alloy body.

TL;DR: In this paper, it was shown that some alloying elements in the zirconium alloys show characteristic emissions which could be used to study their distribution in the ZIRconium oxide.

TL;DR: In this paper, it was shown that the oxygen atoms are present in the interstices of the zirconium lattice and that at high temperatures they have a great mobility in the lattice.
Abstract: Further particulars are given regarding the solubility of oxygen in zirconium (table I). It is shown that the oxygen atoms are present in the interstices of the zirconium lattice and that at high temperatures they have a great mobility in the lattice. Under the influence of an electric field it is found that under suitable conditions of temperature and potential drop the oxygen moves through the metal lattice as a negative ion, causing the oxygen concentration (and with it the electrical resistance) to increase at the anode end and to decrease at the cathode end (fig. 2).

30 May 1991TL;DR: In this article, the authors present a method for controlling the creep rate of ZIRLO material by subjecting the material to a post extrusion anneal, a series of intermediate area reductions and intermediate recrystallization anneals.
Abstract: This invention is for the processing of a somewhat broader range of compositions, including ZIRLO material. It controls creep rate in an alloy having, by weight percent, 0.5-2.0 niobium, 0.7-1.5 tin, 0.07-0.28 of at least one of iron, nickel and chromium and up to 220 ppm carbon, and the balance essentially zirconium. The method is of a type which utilizes subjecting the material to a post extrusion anneal, a series of intermediate area reductions and intermediate recrystallization anneals, with one of the intermediate recrystallization anneals possibly being a late stage beta-quench, a final pass area reduction, and a final stress relief anneal. The creep rate is controlled to about the desired amount per hour by the use of an average intermediate recrystallization annealing temperature and a final pass area reduction combination selected from the designated area of a designated figure, with the figure being selected based on whether the post extrusion anneal was an alpha or a beta anneal; on whether the final anneal was a stress relief anneal or a recrystallization anneal, and whether or not a late stage beta-quench was utilized, and the desired creep rate range. The method may also comprise subjecting the material to an alpha post extrusion anneal and a final stress relief anneal, and controlling the creep rate by the use of certain intermediate recrystallization annealing temperatures and final pass true area reductions.
