NERVA MATERIALS IRRADIATION PROGRAM. VOLUME 1. GTR TEST 16 - AGC MATERIALS TEST
GENERAL DYNAMICS FORT WORTH TX NUCLEAR AEROSPACE RESEARCH FACILITY
The test described in this report was designed to determine the combined effects of nuclear radiation and liquid-hydrogen temperatures on the tensile and shear properties of specific metals considered for structural applications in the NERVA propulsion system. Specimens of the materials were mounted in AGC cryogenic materials pulling assemblies, submerged in liquid hydrogen, and irradiated for close to 200 hr. While still in liquid hydrogen, the specimens were pulled in tension or shear until fracture occurred. After the radioactivity had decayed sufficiently, the specimens were removed and measured for elongation and reduction in cross section. Selected specimens were then subjected to x-ray diffraction and metallographic studies.
