Title: Effect of rare-earth element additions on microstructural properties and irradiation behavior of an Fe-Ni-Cr alloy for LMFBR and fusion reactor applications

Technical Report ·
OSTI ID:5348096

This study consists of a survey of the effect of yttrium, lanthanum, and cerium rare-earth additions on the microstructure and radiation swelling behavior of an Fe-25.6Ni-8.7Cr-3.3Ti-1.6Al alloy. The undoped alloy was investigated in the as-received, annealed, and arc-melted conditions, and twelve arc melted and rare-earth doped alloys were prepared (doping levels of 0.05, 0.1, 0.5, and 1.0 wt % for each of the three rare earths). The ion bombardments were carried out at 570 and 600/sup 0/C with 4 MeV Ni or Fe ions to nominal 100 dpa and to 100 and 550 appm He. Lattice parameter, hardness, swelling, and optical and transmission electron microscopy observations were conducted.
