AB  - The influence of irradiation with He+ ions on the thermal stability of TiZrN and (Ti,Zr)(0.54)Al0.46N nanocrystalline films was studied. The TiZrN and (Ti,Zr)(0.54)Al0.46N films were prepared by reactive magnetron sputtering. XRD research showed that the TiZrN and (Ti,Zr)(0.54)Al0.6N films were single-phase systems (based on cubic c-(Ti,Zr)N and cubic c-(Ti,Zr,AI)N solid solutions) with nanocrystalline (grain size 30 and 21 nm, respectively) structure. The irradiation with He ions and thermal annealing up to 800 degrees C do not affect the structure and phase composition of the (Ti,Zr)(0.54)Al0.46N film. The prior irradiation of the (Ti,Zr)(0.54)Al0.46N film with He+ ions activates spinodal decomposition of the c-(Ti,Zr,Al)N solid solution after thermal annealing at 1000 degrees C due to redistribution of the components of the solid solution inside the grains.

AB  - The phase stability, upon vacuum annealing up to 1000 degrees C, of nanostructured (Ti,Zr)(1-x)SixN thin films is investigated by X-ray diffraction analysis as a function of Si content (0.13 LT = x LT = 0.25) and prior irradiation with He ions (40 kV). The quaternary TiZrSiN thin films were deposited by reactive magnetron sputtering from elemental targets at the substrate temperature of 600 degrees C. It was found that the increase in Si content, x, results in the transformation of structure from nanocrystalline (x = 0.13, grain size of 11 nm) to nanocomposite state (0.190 LT x LT = 0.25, grain size of 5 nm). The phase composition of the films changes from single-phase, cubic c-(Ti,Zr)N columns with (1 1 1) preferred orientation to dual-phase system consisting of c-(Ti,Zr)N crystallites and amorphous SiNy. Irradiation with He ions at the doses of 2 x 10(16) and 5 x 1016 cm(-2) does change the phase composition of the films. It is found that the onset temperature for phase decomposition decreases from 1000 degrees C to 800 degrees C with increasing Si content for unirradiated films. The formation of a secondary ZrN phase is observed concomitantly with increased broadening of the (2 0 0) c-(Ti,Zr)N diffraction peak. For irradiated films, the subsequent annealing at 1000 degrees C leads to decomposition of the c-(Ti,Zr)N solid solution into TiN- and ZrN-rich phases as well as crystallization of hexagonal Si3N4 phase.

AB  - Recent studies have shown that swift heavy ion irradiation may significantly modulate hydrogen and helium behaviour in some materials. This phenomenon is of considerable practical interest for ceramics in general and also for candidate materials for use as inert matrix fuel hosts. These materials will accumulate helium via (n, alpha) reactions and will also be subjected to irradiation by fission fragments. Cross-sectional transmission electron microscopy and scanning electron microscopy was used to study nanocrystalline ZrN irradiated with 30 keV He to fluences between 10(16) and 5 x 10(16) cm(-2), 167 MeV Xe to fluences between 5 x 10(13) and 10(14) cm(-2) and also 695 MeV Bi to a fluence of 1.5 x 10(13) cm(-2). He/Bi and He/Xe irradiated samples were annealed at temperatures between 600 and 1000 degrees C and were analysed using SEM, XTEM and selected area diffraction. The results indicated that post irradiation heat treatment induces exfoliation at a depth that corresponds to the end-of-range of 30 keV He ions. SEM and XTEM analysis of He/Xe irradiated samples revealed that electronic excitation effects, due to Xe ions, suppress helium blister formation and consequently the exfoliation processes. He/Bi samples however do not show the same effects. This suggests that nanocrystalline ZrN is prone to the formation of He blisters which may ultimately lead material failure. These effects may however be mitigated by electronic excitation effects from certain SHIs.
