Description

Various mechanical-property measurements on several grades of manufactured (polycrystalline) graphite stock include tensile-strength determinatftons at temperatures from 20 to 2400 deg C (plus a few at 2500 deg C), tensile stress-strain and creep tests in the range 2000 to 2400 deg C, torsional strength and stress-strain measurements from 20 to 2600 deg C, torsional creep and stress-relaxation tests in the range from 2000 to 2500 deg C, dynamic Young's- modulus determinations from 20 to 2450 deg C, and evaluation of average coefficients of linear thermal expansion for the ranges 20 to 1050 deg C and 1300 to 2400 deg C. ... continued below

The materials studied include a Grade H4LM) molded in 36-in.-diam pieces, both as the standard stock with a nominal density of 1.74 g/cc and as stock re-impregnated to a nominal density of 1.80 to 1.85 g/cc, and four grades of graphite manufactured by the Los Alamos Scientific Laboratory containing normal uranium (added as UO/sub 2/ during the manufacture) in varying concentrations. The tensile-strength and creep data obtained are compared with the results of Los Alamos measurements upon similar materials. (auth)
