Abstract

The binary and ternary intermetallic compounds Zr₃Fe, Zr₂Fe, (Zr_0.5,Nb_0.5)₃Fe, Zr₃(Fe_0.9,Ni_0.1) and Zr₃(Fe_0.5,Ni_0.5) were subjected to 900 keV electron irradiation until amorphous to study the change in the dose-to-amorphization with temperature. The critical temperatures were observed to vary with dose rate, and with the type of compound. Hexagonal (Zr_0.5,Nb_0.5)₃Fe had an appreciably lower critical temperature and higher dose to amorphization at low temperature than orthorhombic Zr₃Fe, whereas other orthorhombic Zr₃(Fe_x,Ni_1-X) compounds were essentially identical in behavior to Zr₃Fe. The electron energy dependence of the dose-to-amorphization was studied in Zr₃Fe between 250 and 900 keV. The analysis of the results gives displacement energies of E_d^Zr = 26 eV, E_d^Fe = 18 eV in the Zr₃Fe compound.
