OSTI ID:10142574
This report describes results of tests on annealed Nitronic 40 stainless steel containing 0.0, 0.26, and 2.6 appM helium-3 (He-3), over the temperature range 25-842 C. Ultimate tensile strength, 0.2% offset yield strength, total elongation, uniform elongation, nonuniform elongation, and reduction-in-area were measured. The predominant effect of He-3 is decreased ductility caused by inhibition of necking. Annealed Nitronic 40 exhibits greater sensitivity to internal He-3 than solution-annealed Incoloy 903 and high-energy-rate forged 316L stainless steel.
