Self-radiation damage in Gd2Ti2O7

Abstract The effects of self-radiation damage from alpha decay in Gd2Ti2O7 were investigated by studying specimens doped with 244Cm. 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 μm in size.
