Abstract

Ni₃Nb and Ni₃Ta intermetallic compounds, which show the complicated lattice structures were irradiated with 16 MeV Au⁵⁺ 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 Ni₃Al and Ni₃V, and was discussed in terms of the intrinsic lattice structures of the samples.
