Based on the results of X-ray structural analysis, changes in the crystalline structure that occurred during 15 years in surface layers of epitaxial films of iron-yttrium garnet implanted by B+ ions were studied. The processes that occur during the B+ ion implantation of in ferrite-garnet films, and the processes that accompany the low-temperature aging of ion-implanted films are considered. Strain profiles were determined from the experimental rocking curves, obtained immediately after ion implantation and after 15 years. It was found that the value of relative maximum deformation of surface layers decreases at constant thickness of the disturbed layer.

Based on the results of X-ray structural analysis, changes in the crystalline structure during natural aging and laser annealing, which occurred in near-surface layers of epitaxial films of LaGa-substituted Iron-Yttrium Garnet, implanted by F+ ions, were studied. The processes that occur during the ion implantation by F+ in ferrite-garnet films, and the processes that accompany the low-temperature aging of ion-implanted films are considered. From the experimental rocking curves, obtained immediately after ion implantation, after the laser irradiation and after several years, strain profiles were determined. Two stages in the changes of the crystalline structure of the nearsurface disturbed layer over time are revealed. During the first of them, the maximum deformation in the ionimplanted layer increased slightly, and on the second it decreased. It was established that the results of laser annealing and natural aging of near-surface layers implanted by F+ ions and laser irradiated LaGa:YIG films  depend on the direction from which laser irradiation occurred. However, the result of their total exposure does not depend on the side of laser irradiation.

Based on the conducted research, it has been found that quenching with hot isostatic pressure and step-by-step aging with consistently increasing temperatures of low-temperature aging (first stage) and high-temperature aging (second stage) provides high tensile strength for AL4MS copper silumin during cold box casting, increases the flow stress by 10%, and maintains high plasticity compared to the level of properties after single-stage aging.

During the 20th century, both dental materials and dental technologies for the fabrication of dental prosthesis progressed remarkably. Owing to the increased demand of safety and aesthetics, 3 mol% yttria stabilized tetragonal zirconia polycrystalline has been recently introduced in prosthetic dentistry for the fabrication of crowns and fixed partial dentures, in combination with CAD/CAM technique. This greatly changed the conventional dental laboratory work which is labor-intensive and experience-dependent. This review mainly introduced the state of dental zirconia and the application of CAD/CAM technology in dentistry.
