“…They indicate that: (i) small defect clusters, which lead to a strong increase of the elastic strain, are created during the first step; (ii) the second step is due to the formation of perfect dislocation loops and of a network of tangled dislocations, inducing a relaxation of the elastic strain and a sharp increase of f D ; (iii) long dislocations, which induce a reorganization of the crystal (decrease of f D ), are exhibited in step 3. A similar behavior (except step 3) was observed in cubic zirconia irradiated with a large variety of low-energy ions [22,23], leading to the conclusion that the number of dpa is the key parameter for the evolution of the damage build-up in the nuclear collision regime. Multi-step damage accumulation processes were also reported in other non-amorphizable ceramics (for instance spinel, magnesium oxide and uranium dioxide) irradiated at low energy [24][25][26][27].…”

Ceramics are key engineering materials in many industrial domains. The evaluation of radiation damage in ceramics placed in a radiative environment is a challenging problem for electronic, space and nuclear industries. Ion beams delivered by various types of accelerators are very efficient tools to simulate the interactions involved during the slowing-down of energetic particles. This article presents a review of the radiation effects occurring in nuclear ceramics, with an emphasis on new results concerning the damage build-up. Ions with energies in the keV-GeV range are considered for this study in order to explore both regimes of nuclear collisions (at low energy) and electronic excitations (at high energy). The recovery, by electronic excitation, of the damage created by ballistic collisions (swift heavy ion beam induced epitaxial recrystallization process) is also reported. 61.80.Jh, 61.82.Ms, 61.85.+p, 68.37.Lp PACS Introductory remarksCeramics are refractory solids which possess very interesting physico-chemical properties, such as high strength, low thermal expansion, chemical stability, strong resistance against oxidation, good behavior under irradiation, etc. These materials are therefore often employed in hostile media where efficient use of energy is a prime need, e.g. extreme temperatures, corrosive surroundings, radiative environment, etc. Examples of the interest of ceramics for applications are provided by electronic, space and nuclear industries. For instance, such materials are nowadays widely used for surface coating and electronic packaging, and they are envisioned in a near future for the safe and long-term disposal of radioactive waste, and the development of inert fuel matrices for actinide transmutation. They may also be employed as cladding materials for gas-cooled fission reactors and structural components in fusion reactors. For all these applications, there is an urgent need of data concerning the behavior of nuclear ceramics upon irradiation.The topic that is concerned here is so broad that it requires a whole book to cover the main issues; the state of knowledge was regularly upgraded in thorough reviews [1][2][3][4][5][6][7][8][9][10]. To deal it in a short article, we focus on the presentation of a few remarkable examples concerning the ion-beam modifications of nuclear ceramics (zirconia, pyrochlores, silicon carbide, etc.) with an emphasis on the mechanisms leading to damage cre- * corresponding author; e-mail: thome@csnsm.in2p3.fr ation and phase transformations. We report typical results obtained using advanced characterization techniques (the Rutherford backscatteringspectrometry associated to channeling (RBS/C), X-ray diffraction (XRD), transmission electron microscopy (TEM), Raman) for ceramics irradiated with ions in a broad energy range (from keV to GeV) in order to explore both nuclear collision and electronic excitation regimes.The first section is devoted to the presentation of general considerations about the damage build-up in ion--irradiated crystals and of a new mo...

“…Although He and Xe ion fluences are very close, leading to almost identical noble-gas concentrations in the implanted layer in both cases, this result can be accounted for by the huge difference in the energy deposited in nuclear collisions, leading to very different number of dpa created by incoming ions (Table 1). In a recent paper Thomé et al measured, by Rutherford backscattering and channeling (RBS/C) experiments, the damage accumulated in cubic yttria-stabilized zirconia single crystals (structure isomorphic of the UO 2 one) irradiated with various noble-gas ions [23]. The results show the presence of several disordering stages scaled with the number of dpa.…”

“…More information on how these results were obtained is given in Ref. [19]. This disordering kinetic exhibits three stages: (i) a first plateau characterized by a very low damage level at low dpa (i.e., low fluences); (ii) a sharp rise of f Zr D at 3 dpa and (iii) a slowly rising plateau above 4 dpa.…”
