OSTI ID:10109280
Tensile testing on model Fe-Cr-Ni alloys removed from four discharges of the {sup 59}Ni isotopic doping experiment in FFTF indicates that helium/dpa ratios typical of fusion reactors do not produce changes in the yield strength or elongation that are significantly different from those at much lower helium generation rates. It also appears that tensile properties approach a saturation level that is dependent only on the final irradiation temperature, but not prior temperature history or thermomechanical starting condition. 14 refs., 4 figs., 1 tab.
