“…However, such studies for nuclear power plants and space developments have treated the negative effects of ion irradiation (so-called "radiation damage") on materials' properties. In our recent studies, we have positively used the energies deposited by energetic ion/electron irradiation for the modification of materials properties such as the mechanical properties [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23], magnetic properties [24][25][26][27][28][29][30][31][32][33][34][35][36][37], and optical properties [38] of metallic and oxide materials.…”

When materials are irradiated with high-energy ions, their energies are transferred to electrons and atoms in materials, and the lattice structures of the materials are largely changed to metastable or non-thermal equilibrium states, causing the modification of several physical properties. There are two processes for the material modification by ion irradiation; one is “the irradiation-enhanced process”, and the other is “the irradiation-induced process”. In this review, two kinds of recent results for the microstructural changes and the modifications of mechanical properties will be summarized: one is the hardness modification of dilute aluminum alloys, which is a result of the irradiation-enhanced process, and the other is the hardness modification of Ni-based intermetallic compounds as a result of the irradiation-induced process. The effect of the subsequent thermal treatment on the microstructures and the hardness for ion-irradiated dilute aluminum alloys is quite different from that for Ni-based intermetallic compounds. This result reflects the difference between the irradiation-enhanced process and the irradiation-induced process. Finally, possibilities of the ion irradiation and subsequent thermal treatment to industrial applications will also be discussed.

Amorphous alloys are expected to be useful for various applications because they have superior mechanical properties such as strength, hardness and corrosion resistance. So far, the only method for production of amorphous metals is to quench from the liquid state. When materials are exposed to high-energy ions, the lattice structures of the materials tend to be metastable or non-thermally equilibrium, and in some cases, they lose the crystallinity, resulting in amorphization. However, the alloy types and irradiation conditions that cause amorphization by irradiation have never been well clarified yet. In order to study the amorphization by particles irradiation as one of the material processes such as strength control, we have studied the structural changes and the accompanying hardness changes of the bulk crystalline alloys due to various irradiation conditions. In this paper, we discuss the correlation between amorphization and hardness change when heavy ion irradiation is applied to several intermetallic compounds.
