Abstract
Irradiation tests were performed on Haynes Stellite Alloy 25 and Inconel-X springs irradiated in the compressed condition in an in-pile high-temperature water loop. The loop was operated at 560 to 600 F and the springs of both materials received integrated fluxes of 5.9 × 1018 and 4.2 × 1019 nvt fast, respectively. Postirradiation testing and examination revealed no serious deleterious effects resulting from these exposures. It was found the spring constant increased 5 to 8 per cent after exposure and the free length decreased 2 to 3 per cent. The effect of irradiation on the plastic-flow curve was slight as revealed by three-point loaded bend tests on 0.160-in-diam rods irradiated with the springs.Keywords
