The binary and ternary intermetallic compounds Zr{sub 3}Fe, Zr{sub 2}Fe, (Zr{sub 0.5},Nb{sub 0.5}){sub 3}Fe, Zr{sub 3}(Fe{sub 0.9},Ni{sub 0.1}) and Zr{sub 3}(Fe{sub 0.5},Ni{sub 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{sub 0.5},Nb{sub 0.5}){sub 3}Fe had an appreciably lower critical temperature and higher dose to amorphization at low temperature than orthorhombic Zr{sub 3}Fe, whereas other orthorhombic Zr{sub 3}(Fe{sub x},Ni{sub 1{minus}x}) compounds were essentially identical in behavior to Zr{sub 3}Fe. The electron energy dependence of the dose-to-amorphization was studied in Zr{sub 3}Fe between 250 and 900 keV. The analysis of the results gives displacement energies of E{sub d}{sup Zr} = 26 eV, E{sub d}{sup Fe} = 18 eV in the Zr{sub 3}Fe compound.
