“…The nucleation behavior and the heterogeneous mobility of grain boundaries may result in different distributions of grain shapes and sizes. As nucleation and growth both critically depend on the thermo-mechanical history of the samples prior to annealing, recrystallization is commonly used to tailor microstructures and improve mechanical properties (e.g., References [1][2][3][4][5][6][7]). However, it is still not fullly understood how the kinetics of recrystallization and the characteristics of recrystallized microstructures are affected by different factors.…”

During static recrystallization, grains often have non-constant and non-uniform growth rates, significantly affecting the recrystallization kinetics and the microstructure after recrystallization. A cellular automaton model was employed in order to evaluate the relative influences of gradients of stored energy, grain boundary curvature, and heterogeneity of grain boundary mobility on the non-uniform migration of grain boundary segments, leading to the formation of protrusions and retrusions. Electron back-scatter diffraction measurements of a cold-rolled copper microstructure served to feed the model. Orientation maps obtained after partial recrystallization were used to assess the model outcome. The model was capable to predict the shapes of recrystallized grains with retrusions and protrusions. Effects of different model assumptions were compared to reveal individual contributions of different factors to grain size distribution, grain shape and boundary roughness. The model predicted a decreasing average grain growth rate as a result of the progressive immobilization of an increasing fraction of grain boundary segments. The model prediction was compared with experimental results, explaining the origin of stationary boundaries and indicating some further improvements necessary to reach quantitative agreement.

“…Shin et al [ 17 ] obtained a heterogeneous‐structured Ti alloy via cold rolling and annealing and found that plastic incompatibility between soft and hard domains could result in large stress and strain gradients, as well as an exceptional combination of strength and ductility. Xie et al [ 18 ] found that DSS with HL structures had improved mechanical properties, which were due to the grain refinement and back stress arising from the microstructural heterogeneity. Compared with their mechanical properties, the corrosion performance of HL‐structured materials has received much less attention.…”

Heterostructured (HS) materials, characterized by heterogeneous zones with differences in mechanical or physical properties, represent a revolutionary advancement in material science. During deformation, hetero‐deformation‐induced (HDI) stress forms due to the synergistic interactions between soft and hard zones, leading to remarkable HDI strengthening and strain hardening. This mechanism significantly enhances their performance, surpassing that of traditional homogeneous materials. This review delves into the classification, preparation techniques, fundamental deformation mechanisms, and research methods of HS materials. It outlines the preparation methods of various HS materials, emphasizing their unique characteristics and applications. The review elaborates on the fundamental deformation mechanisms of HS materials, focusing on non‐uniform plastic deformation behavior and HDI strain hardening. Furthermore, it explores the application of heterogeneous design concepts in materials, analyzing their microstructure tuning mechanisms and mechanical properties. This review aims to serve as a critical reference for the future design and development of new HS metallic structural materials, paving the way for innovations that can transform multiple industries. By highlighting the long‐term impact, this review not only enhances the understanding of HS materials but also provides a roadmap for future research and industrial applications, positioning HS materials as key players in the advancement of material technology.
