BERYLLIUM ALLOYS

Patent ·
OSTI ID:4064667

Alloys of beryllium containing from 0.05 to 3.0 wt% titanlum or zirconium were prepared to provide a beryllium-base material that has good corrosion resistance to moist, hot carbon dioxide without substantially sacrificing the neutron transparency of the material. The alloys also The corrosion resistance of gamma-phase U base alloys containing Mo and/or Nb to water and steam may be increased by adding small amounts of Pt. Preferred compositions are (Mo + Nb) 5 to 12%, Pt 0.5 to 2%, and balance U. The fabrication of such alloys for use in reactor fuel elements include hot working, a homogenizing anneal at approximates 900 deg C, and a further anneal for 77 days at 350 to 525 deg C. The effects of 0.3, 0.6, and 1.2% Pt additions to U-9% Mo alloys on their corrosion rate in hot water at 650 deg F are shown graphically. Zr alloy claddings suitable for fuel elements utilizing the U base alloys are considered. (D.J.C.)
