Definitions

  • Zirconium alloys in accordance with the present invention contain 0.51.5% by weight of copper, and from 0.25-1.5% by weight of molybdenum or chromium, the
  • Example 2Cu, 1.0%; M0, 1.5%; remainder Zr The following mechanical properties of the improved alloys in comparison with zirconium and Zircaloy-2 are as follows:
  • V.P.N. Vickers Pyramid Number
  • Alloy 3 30 300 3,000 secs. secs. secs. secs.
  • Example 1 alloy was slightlyhardcr for the longest-period of load application, and slightly less hard for the shorter periods of 5 load application than Zircalo'y-Z.”
  • Specimens of Example 1 alloy were about 20% better, and of Example 2 alloy about better than those of Zircaloy-2," the percentage elongation of specimens of Example l was about the same as that of Zircaloy-Z, while that of Example 2 was about two-thirds that of Zircaloy 2. This improvement was increased when the specimens were tested at 375 C.
  • Example 1 and Example 2 are 0.012386 cm.- and 0.015126 cm.- respectively.
  • the high temperature mechanical properties of zirconium-copper-molybdenum and zirconium-copper-chromium alloys mentioned above can be further improved by heat treatment, which consists of heating the alloy to a temperature of 850 C. to 950" C. and maintaining the temperature for a specified time before quenching to reduce the temperature of the alloy rapidly. This treatment may then be followed by a tempering treatment which consists of reheating the alloy for a specified time at a temperature below 850 C.
  • the constituents of the alloy should be melted in a vacuum arc furnace.
  • the alloys of the invention can be readily fabricated by conventional methods.
  • Impurities in the base zirconium sponge should be kept to a minimum.
  • the most deleterious impurities from the corrosion resistance point of view are. aluminium, silicon, hydrogen, xygenr i s n. a it ni m. l minium should be kept below 150 parts per million, whilst nitrogen and'titanium are not so injurious, and in the latter case, and titanium content may be as high as 1,000
  • An alloy consisting of 0.5 to 1.5% by weight of copper, 0.25 to 1.5% by weight of a metal selected from the group consisting of chromium and molybdenum, and the remainder zirconium except for unavoidable impurities.
