ABSTRACT
The order-disorder transition of quasicrystalline Al86Mn14 under 1 MeV electron irradiation at 135 K was investigated. The dose required to completely amorphize an area was found to depend on the axis aligned with the beam. Analysis showed that, for a given orientation, the transition obeyed the excluded volume theory of disordering. The dose required was not directly proportional to the current density which indicates that some recovery takes place during irradiation.
