Description	Hagihara K., Ueyama R., Tokunaga T., et al. Quantitative estimation of kink-band strengthening in an Mg–Zn–Y single crystal with LPSO nanoplates. Materials Research Letters, 9, 11, 467. https://doi.org/10.1080/21663831.2021.1974593.
Abstract	Kink-band strengthening was first quantitatively evaluated using an Mg–Zn–Y single crystal containing long-period stacking ordered (LPSO) nanoplates. The ability of a kink-band boundary to act as a barrier that hinders the motion of dislocations is high and comparable to that of a general random grain boundary. Nevertheless, a kink-band boundary is regarded as a simple tilt boundary in the dislocation model. One reason for the anomalous ability of kink-band boundary acting as barriers is related to its peculiar hierarchical structure, in which many small kink bands with high crystal rotation angles accumulate in a localized region.
