OBRABOTKAMETALLOV MATERIAL SCIENCE Vol. 24 No. 4 2022 b Fig. 19. Models of flaking mechanism from extended inclusion [39]: a – sample with short vertical inclusions (low concentration of S); b – sample with horizontal inclusions а Conclusion An analysis of the experiments based on using synchrotron radiation sources indicates the effectiveness of the methods of synchrotron computed tomography (SRCT) and synchrotron computed laminography (SRCL) when conducting research in the field of modern materials science. The SRCL method provides the possibility of monitoring the structure of materials when implementing various loading schemes including the study of fatigue and contact fatigue fracture processes. Implementation of the SRCT and SRCL methods is reasonable at the Siberian Ring Photon Source, which is under construction in Novosibirsk. The planned parameters of this source will make it possible to obtain images of the structure of structural and functional materials with high spatial resolution. References 1.
