Irradiation effects on reactor structural materials. Quarterly progress report, 1 February--30 April 1973

Technical Report ·
OSTI ID:4330009
The research program of the NRL Metallurgy Division, Reactor Materials Branch, involves a broad study of the effects of nuclear radiation on materials. The report covering research for the period 1 February to 30 April 1973, and includes: the effect of hold time on fatigue crack propagation in 20% cold worked stainless steel; the effect of implanted helium on fatigue behavior of TZM alloy; radiation enhanced metastability in a high strength structural alloy, tbe AEC-CE- NRL Cooperative program on A533-B reactor vessel steel; the transition temperature increase for the SM-1A pressure vessel at reactor shutdown; J- integral characterization of the SM-1A reactor pressure vessel steels; the effect of water vapor on the fatigue strength of irradiated Type 348 stainless steel; and the effect of beam scanning on void formation in nickel-ion bombarded nickel.
