“…This broadening is likely to be attributed to microstrains induced by irradiation. The lattice stretching along the c-axis as well as the intensity drop of 000 peaks are in good agreement with results already reported in the litterature [9,11,12].…”

“…In parallel, a growing intensity of the 0002 peak is clearly evidenced. These evolutions are interpreted as a recovery of the MAX phase structure, which is in good agreement with the beginning of defect annealing from 300 • C reported in Ti 3 SiC 2 [12] and Ti 3 Si 0.90 Al 0.10 C 2 [9]. Up to 800 • C, this peak keeps on shifting till a position (2θ= 39.91 • ) close to the 0008 peak of Ti 3 AlC 2 in the initial state (2θ i = 38.66 • for the non-irradiated film).…”

“…The 0008 shift is accompanied with a higher intensity of this additional peak up to 1.5×10 15 Ar.cm −2 . The diffraction at a higher order is also visible, as indicated in Fig [9]. In the present case, not only the relative intensities evolve but a supplementary peak is induced by the irradiation process.…”

“…There are only few studies about the behavior of MAX phases under ion irradiation, almost exclusively focused on Ti 3 AC 2 (A = Si, Si 1−x Al x , Al) [7,8,9,10,11,12,13,14,15], in addition to (Ti 0.95 Zr 0.05 ) 3 SiC 2 [16] and (Ti,Al)N/Ti 2 AlN x multilayers [17]. They highlight a strong tolerance to damage induced by ion irradiation and a retained crystalline structure, to the exception of Cr 2 AlC and Cr 2 GeC, which amorphize at moderate fluence (10 13 -10 14 Xe.cm −2 ) [18].…”

Contribution of core-loss fine structures to the characterization of ion irradiation damages in the nanolaminated ceramic Ti3AlC2

The effect of low energy ion irradiation in the nanolaminated Ti 3 AlC 2 is investigated by means of X-ray diffraction, transmission electron microscopy, electron energy loss and X-ray absorption spectroscopy. The chemical sensitivity and local order probing from core-loss edges provide new insight in the undertanding of structural modifications induced under irradiation. From the analysis of the C K energy loss near edge structure (ELNES) and Al K X-ray absorption near edge structure (XANES) by ab initio calculations, the influence of the layered structure of this compound on the irradiation damage is demonstrated, with preferentialy localized damage in aluminum planes of the structure. On the basis of comparisons between calculations and the experimental spectra, a strutural model is proposed for the irradiated state. This study emphasizes the utility of core-loss fine structure analysis to further understanding of ion irradiation induced damage in complex crystalline materials.

“…Moreover, this material with behaviour at the frontier between ceramics and metals, presents thermal properties fitting all the specifications required for this cladding: its decomposition temperature varies in the literature between 1400 and 1700 °C [11,16,17], it is thermal shock resistant [10,16], and presents a thermal conductivity above 30 W m -1 K -1 at the nominal working temperature of GFR [17]. However, to date few studies have been conducted on Ti 3 SiC 2 behaviour under irradiation [18][19][20][21].…”

In the framework of the Generation IV International Forum, carbides are sensed for the design of the fuel cladding of the Gas-cooled Fast Reactor. Among the studied carbides, Ti 3 SiC 2 has the advantage of combining the properties of both metals and ceramics. After performing irradiations with 92 MeV Xe ions to 10 19 m -2 , hills were observed by AFM on the surface of Ti 3 SiC 2 . Such topographic modification seems to have never been observed in other materials irradiated in such conditions. A characterization of these hills by both XPS and X-TEM highlighted that these surface modifications do not appear in Ti 3 SiC 2 but in a native amorphous oxide layer on the sample. Moreover, the thickness of this oxide layer grows under irradiation. The comparison between different irradiations permitted to conclude that this surface modification is due to electronic interactions in this amorphous layer, and a threshold in electronic stopping power for hill formation is evidenced.
