Abstract
The presented contribution referred to basic effects of 150 keV proton irradiation on ready prepared FIM tips of Cu-Be and Cu-Ni-Fe alloys. Dilute solid solutions of Be in Cu are known to form incoherent precipitates of the γ phase (B2 structure) upon heavy ion irradiation /1/. Electron irradiation, however, induces G.P. zone formation 121. While the radiation-induced γ precipitation has been studied in great detail and seems to be understood quantitatively /3/, important parameters are still unknown for the electron irradiation case.
