The simulation of neutron irradiation damage with charged particles (protons and electrons) is investigated, using the crystalline- amorphous transformation of intermetallic precipitates in zircaloy as a standard. The precipitates were found not to amorphize under proton irradiation up to 1.5 dpa at temperatures between 360 and 470 K. Irradiation-induced precipitation of tin was observed in some samples. Under electron irradiation the precipitates became amorphous at doses that increased exponentially with temperature and decreased with dose rate. A theoretical model based on the accumulation of the electrons under irradiation was developed that well explains the electron irradiation results. 30 refs.
