“…Therefore, different from the change in the relative degree of order, the change in Vickers hardness cannot be described only by considering the density of energy deposited through elastic collisions. For Ni 3 V, Au ion irradiation induces an order-disorder lattice structure change and this accompanies a similar decrease in Vickers hardness [5][6]. The decrease in hardness for irradiated Ni 3-Al is, however, much smaller than that for irradiated Ni 3 V. This difference in the decrease in hardness between the two kinds of intermetallic compounds can be explained by considering that Ni 3 V has the D0 22 lattice structure at room temperature and a hard lamellar-like microstructure exists in Ni 3 V [19].…”

“…In our previous study, two intermetallic compounds, Fe 55 Rh 45 and Ni 3 V, were irradiated with 16-MeV Au ions [4][5][6]. Fe 55 Rh 45 has the B2 (bcc base) lattice structure and Ni 3 V has the D0 22 (fcc base) lattice structure as thermal equilibrium phases at room temperature.…”

“…When the annealing treatment was performed at even higher temperatures, the peaks corresponding to the intrinsic monoclinic structure would be observed, and the hardness would recover to the value before the irradiation. We have previously reported the recovery of the irradiation-induced lattice structure change by the thermal annealing in Ni3V and Ni3Al intermetallic compounds [12,13]. In the case of Ni3V, the random fcc structure induced by the ion irradiation recovers to the intrinsic tetragonal structure (D0 22 structure) by the annealing at 773K.…”

To investigate the thermal stability of the ion-irradiation induced amorphous state in bulk samples of Ni3Nb and Ni3Ta intermetallic compounds, they were irradiated with 16MeV Au ions at room temperature, and were subsequently annealed up to 773K and 973K, respectively. The lattice structures of the irradiated samples and the annealed samples were examined by means of the grazing incidence x-ray diffraction (GIXD). The hardness of the samples was also measured as a function of annealing temperature. The amorphous state induced by room temperature irradiation recovers to the intrinsic ordered structure for Ni 3 Nb samples at 773K. On the other hand, for Ni3Ta samples, the irradiation-induced amorphous state doesn't recover to the intrinsic ordered structure even at 973K, but it changed to another lattice structure by the subsequent annealing. The values of the hardness decreased by the subsequent annealing. For Ni3Nb samples, the irradiation at elevated temperatures was also performed. The higher temperature irradiation tends to suppress the amorphization more strongly in Ni3Nb samples. As a result, the increase in hardness becomes smaller for the higher temperature irradiation.

“…They are promising as a next generation type of high temperature materials and it is needed to investigate not only structure transformation, but also mechanical property. In our previous results, we showed the lattice structure transformation, which was induced by energetic ion irradiation, and the change in Vickers hardness for Ni 3 Al 32) , Ni 3 V 33,34) , Ni 3 Nb and Ni 3 Ta 35) intermetallic compounds. At room temperature, Ni 3 V intermetallic compound shows the tetragonal ordered structure (D0 22 structure), and Ni 3 Al intermetallic compound shows the cubic ordered structure (L1 2 structure).…”

“…At room temperature, Ni 3 V intermetallic compound shows the tetragonal ordered structure (D0 22 structure), and Ni 3 Al intermetallic compound shows the cubic ordered structure (L1 2 structure). However, both ordered structures change into the disordered fcc structure (A1 structure) by the energetic ion irradiation [32][33][34] . While for Ni 3 Nb and Ni 3 Ta intermetallic compounds, the lattice structures transformed from the ordered orthorhombic or monoclinic structure to the amorphous state by the ion irradiation 35) .…”

Bulk samples of Ni 3 Nb and Ni 3 Ta intermetallic compounds were irradiated with 16 MeV Au, 4.5 MeV Ni, 4.5 MeV Al, 200 MeV Xe and 1.0 MeV He ions, and the change in near-surface lattice structure was investigated by means of the grazing incidence x-ray diffraction (GIXD) and the extended x-ray absorption ne structure (EXAFS). The Ni 3 Nb and Ni 3 Ta lattice structures transform from the ordered structures (orthorhombic and monoclinic structures for Ni 3 Nb and Ni 3 Ta, respectively) to the amorphous state by the Au, Ni, Al and Xe ion irradiations. Irrespective of such heavy ion species or energies, the lattice structure transformation to the amorphous state almost correlate with the density of energy deposited through elastic collisions. In the case of the samples irradiated with 1.0 MeV He ions, however, no amorphization was observed even when the density of elastically deposited energy is the same as that for Au irradiated sample which showed the amorphous phase. The change in Vickers hardness induced by the amorphization was also measured and was discussed in terms of ion uence and the density of deposited energy.
