Times Cited Count:9 Percentile:65.1(Instruments & Instrumentation)NiNb and NiTa intermetallic compounds, which show the complicated lattice structures were irradiated with 16 MeV Au ions at room temperature. The X-ray diffraction measurement revealed that the lattice structure of these intermetallic compounds changed from the ordered structures to the amorphous state by the ion irradiation. The irradiation-induced amorphization caused the increase in Vickers hardness. The result was compared with our previous results for NiAl and NiV, and was discussed in terms of the intrinsic lattice structures of the samples.
