Abstract

The effects of self-radiation damage from alpha decay in Gd-2Ti-2O-7 were investigated by studying specimens doped with 244 Cm. The radiation-induced microstructure consists of individual amorphous tracks from both the alpha recoil particles and the spontaneous fission fragments. The eventual overlap of the tracks at higher doses leads to a completely amorphous state. The self-radiation damage increases the volume, dissolution rate, and fracture toughness. Electron beam recrystallization of the amorphous state results in the formation of fine microcrystallites on the order of 0.05 Mm in size.
