Irradiation Effects on Reactor Structural Materials.
Abstract
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.
