Transmission electron microscope specimens of the oxide superconductors YBa2Cu3O7 and GdBa2Cu 3O7 have been irradiated at 35 K with 1 MeV electrons and doses up to 1.5×1023 e/cm2. Electron diffraction data show the two different superconductors do not respond similarly with GdBa2Cu3O7 being more resistant to amorphization than YBa2Cu3O7. Amorphization appears to be dependent on displacements occurring at the Y/Gd lattice site. In addition, it appears that within each material, the electron dose required to initiate amorphization is lower for grain boundary irradiations relative to large single grain irradiations.
