The mechanical properties of two aluminum alloys and a fuel dispersion have been investigated for the purpose of selecting a cladding material and supplying data for design evaluation of the Advanced Test Reactor fuel plates. The properties of the X8001, 6061, and the U/sub 3/O/sub 8/--Al dispersion were investigated. The creep properties of these materials in uniaxial tension were measured in the temperature range of 400 to 600 deg F for maximum strains of 1.0% and times of 450 hr. The tensile properties were measured from 70 to 600 deg F. The 6061-0 is stronger in short-time tension and creep than the X8001-0 material. The tensile strength of X8001 can be increased by cold working. Recovery of the cold-worked X8001 and 6061 alloys was investigated and compared with the kinetics of the overaging of the 6061 alloy in the T6 condition. The fuel dispersion is stronger in creep than the X8001-0 matrix material. The tensile strength of the fuel dispersion is approximately twice that of X8001-0. (auth
