Swelling of high-nickel Fe-Ni-Cr alloys in EBR-II (Contribution to DAFS quarterly)
The objective of this effort is to identify the origins of the compositional dependence of swelling in simple ternary alloys. Swelling data on Fe-Ni-Cr alloys with nickel in the 35 to 75 wt % range has been obtained to fluences as large as 2.2 x 10/sup 23/ n/cm/sup 2/ (E > 0.1 MeV) (approx. 110 dpa). At 15% chromium the swelling rate at 35, 45 and 75% nickel continues to increase with accumulating exposure, most clearly approaching 1%/dpa at approx. 35% nickel. The minimum often observed in swelling at approx. 45% nickel appears to be due to a maximum in the duration of the transient regime at this composition. Decreasing the chromium level from 15 to 7.5% extends the transient regime even further.
