Abstract:

The research program involves a broad study of the effects of nuclear radiation upon materials. The report, covering research for the period 1 February - 30 April 1972, includes 1 electron microscopy observations of radiation damage in pressure vessel steels and iron alloys, 2 the effect of neutron irradiation on fatigue crack propagation in austenitic stainless steel at high temperature, 3 a study of radiation reduction in notch toughness of stainless steel submerged arc weldments, 4 the effect of cyclotron-injected helium on the fatigue properties of 316 stainless steel, and 5 preliminary results from an environmental exposure of fandidate CTR first-wall structural alloys.
