“…The properties in such nanoscale regions containing lattice disorder or an amorphous phase are drastically changed and modified compared with the surrounding virgin bulk. Thus, swift heavy ion irradiation is a powerful technique that is utilized to study the undesirable phenomena (creep, swelling, embrittlement, etc) occurring in irradiation environments [12][13][14][15][16] but also has beneficial applications in material modification and device fabrication on the nano-and micrometer scales [17][18][19][20][21][22][23][24][25][26][27][28][29][30][31]. Alkali tantalate crystals (KTaO 3 , LiTaO 3 , etc) with perovskite-like structures exhibit versatile properties that are attractive for numerous applications, such as electro-optic waveguides in microelectronics [32], pyroelectrics in neutron generation [33] and photocatalysts in pollutant degradation [34] and water splitting [35].…”

The formation of latent tracks with different damage morphologies in alkali tantalate crystals (KTaO3 and LiTaO3) under the action of the extreme electronic energy loss induced by 358 MeV 58Ni19+ irradiation was studied by experimental characterizations of the lattice damage and numerical calculations using the inelastic thermal spike model. Prism coupling measurements were used to analyze of the refractive index profiles of irradiated regions. This approach is effective and very accurate for determination of the in-depth damage profile and its correlation with the energy loss curves. The calculated spatio-temporal evolution of the energy deposition densities and lattice temperatures theoretically demonstrate the experimentally observed latent tracks in Ni19+-irradiated crystals. Based on the observed damage morphologies of individual and overlapped spherical defects, and discontinuous and continuous tracks, the corresponding threshold values of the electronic energy loss for track damage in alkali tantalate crystals were assessed. For irradiating ions with an energy of 6.17 MeV amu–1, a threshold of ~12.0 keV nm−1 for the production of spherical defects in KTaO3 crystals is indicated, and the threshold for LiTaO3 crystals is less than 12.0 keV nm−1. For irradiating ions with an energy of 2.15 MeV amu–1, owing to the ion-velocity dependence effect, an electronic energy loss of ~13.8 keV nm−1 leads to overlapped spherical defects and discontinuous tracks in KTaO3 and continuous tracks in LiTaO3. Compared with LiTaO3, a relatively higher damage tolerance and critical threshold for track formation in KTaO3 crystals are proven. The determined lattice temperature threshold for continuous track production is 3410 K for KTaO3 and slightly less than 3250 K for LiTaO3, demonstrating that, compared with the melting point, a much higher lattice temperature in the region surrounding the ion path needs to be achieved to produce stable track damage due to the non-negligible effect of melting damage caused by annealing during the cooling process.

The validation of a ball-on-ring, equibiaxial flexural strength method to obtain the transverse rupture strength (TRS) of right cylindrical ceramic specimens was performed in this study. Validation of the test method was achieved using commercially available engineered high purity alumina disks and finite element (FE) model analysis. The validated fixture was then used to obtain the TRS and Weibull statistical analysis of MgOpartially stabilized zirconia (MSZ) and Y 2 O 3-partially stabilized zirconia (YSZ) ceramic disks. TRS data for alumina, MSZ, and YSZ agreed with the TRS values reported in the literature. A statistically relevant number of samples (N>30) for each material were tested to allow for a Weibull statistical analysis. Weibull parameters for these materials were within the expected values for engineered ceramics. The characteristic strength for alumina, MSZ, and YSZ were determined to be 289 MPa, 786 MPa, and 814 MPa, respectively. The Weibull modulus was determined between 10-25 for each material, which is typical of engineered ceramics. In addition, Accepted Article This article is protected by copyright. All rights reserved FE model results were in close agreement with experimental fracture values for the three ceramic materials tested in this study.
