Effect of radiation damage on cyclic crack resistance of austenitic steels and alloys (review)
Description
Results of experimental studies of cyclic crack resistance of austenitic steela and nickel alloys in annealed and hot-deformed states at different temperatures and doses of radiation damage are analyzed and generalized. High-temperature aging of annealed steels promotes a decrease of the crack growth rate while a preliminary cold deformation does not play a noticeable role in preserving cyclic crack resistance after radiation under loading in the region of the lowered temperatures and is of negative effect at temperatures above 600 deg C. A decrease of the load frequency or the presence of holdings in a cycle under stress intensity coeffient equal to Kmax essentially decreases fatigue crack growth resistance while the radiation damage enhances this effect
