【 摘 要 】

Alkrothal 720 and KanthalAPMT(TM), twb commercial FeCrAl alloys, were neutron irradiated up to damage doses of 7.0 displacements per atom (dpa) in the temperature range of 320 to 382 degrees C to characterize the alpha' precipitation in these alloys using small-angle neutron scattering. Both alloys exhibited alpha' precipitation. Kanthal APMTSM exhibited higher number densities and volume fraction, a result attributed to its higher Cr content compared with Alkrothal 720. Trends observed as a function of damage dose (dpa) are consistent with literature trends for both FeCr and FeCrAl alloys. (C) 2017 Acta Materialia Inc. Published by Elsevier Ltd.
