“…Type 2 unpinning resembles behavior seen in previous work on cascade, thermal spike, and shock wave effects on straight dislocations. The dislocation motion triggered by a cascade (or a shock wave) toward the cascade center (or the wave source) was reported by several authors for different metals through MD simulations [20,22,25,24,23]. Cascade induced glide of dislocations was also theoretically investigated by Trinkaus [36] and Zhukov and Boldin [37].…”

“…Starostenkov et al [23] investigated the post cascade shock wave effect on a single edge dislocation or on an ensemble of edge dislocations in nickel, and the authors observed the glide of the dislocations toward the wave source. Korchuganov et al [24,25] found that a shock wave generated near an edge dislocation under applied stress in iron induces dislocation glide toward the wave source. The authors concluded that this phenomenon can contribute to irradiation creep.…”

“…At the same time, the observed discrepancies in some profile parameters, particularly, in the values of strain profile maxima found in two independent ways can be used to refine and improve the various procedures for simulating the creation of primary and secondary radiation defects (see, e.g., Refs. ).…”

The generalized dynamical theory of X-ray diffraction by imperfect single crystals is extended to characterize structure imperfections of real single crystals with complex basis and similar crystalline films with inhomogeneous strain fields. The influence of various defects (intrinsic and extrinsic point defects, nanoclusters, and microdefects), simultaneously presented in such structures, on changing both average and fluctuating strain fields as well as structure factors are taken into account. The analytical expressions connecting immediately the coherent and diffuse components of the scattering intensity with statistical characteristics of these defects are obtained. Thus, the self-consistent description of the coherent and diffuse dynamical diffraction intensity components is provided. Some examples of the application of the developed theoretical model to treat rocking curves measured from various garnet structures by using high-resolution double-crystal X-ray diffractometer are reviewed. Possibilities for the quantitative characterization of structural defects and strain profiles in the as-grown and ion-implanted garnet single crystals and yttrium iron garnet films are demonstrated.The self-consistent dynamical description of coherent and diffuse scattering intensities from imperfect crystal structures with inhomogeneous strain fields and randomly distributed defects make it possible to determine the parameters of strain profiles and statistical characteristics of defects by analytical treating the coherent and diffuse components of rocking curves measured by the high-resolution double-crystal X-ray diffractometer with widely open detector window.
