The research program of the NRL Metallurgy Division, Reactor Materials Branch, involves a broad study of the effects of nuclear radiation upon materials. This report, covering research for the period 1 November 1971-31 January 1972, includes 1 a study on fatigue crack growth rates in several 300 series stainless steels, 2 the effect of irradiation on the fatigue properties of thin section Type 348 stainless steel at 550F 288C, 3 an evaluation of notch toughness of AISI Type 304 and 316 stainless steel submerged arc weldments, 4 description of a subsize R-specimen for assessments of postirradiation fracture extension resistance, 5 electron microscopy observations of the postirradiation microstructure of pure iron and dilute iron alloys 6 mechanisms of vacancy generation in laser bombarded targets, and 7 the cyclotron simulation of helium transmutation damage in 304 stainless steel.
