“…The XRD results of the as-cast, solution-treated, and cryorolled composites and their comparative studies were reported in the authors' previous work. [16,30] In the present study, at an annealing temperature of 423 K, no significant changes in XRD maps were observed in the UFGB and UFG composite materials. However, a low-intensity peak of the Mg 2 Si precipitate was observed after an annealing temperature of 473 K in all UFG materials.…”

“…The UFGCC consisted of densely packed dislocations in regions surrounding coarse SiC particles and dislocation cells (125 ± 50 nm) in the matrix region away from SiC particles (Figure 3(b)), which was also reported in the authors' previous work. [16] A polygonized cell structure around the SiC particles was observed in the UFGFC (Figure 3(c)). The existence of subgrains was also observed in the UFGFC along with the reduced size of dislocated cell structure (90 ± 25 nm) compared to the UFGCC.…”

“…The details of the stir-casting and cryorolling processes to fabricate UFG AA6063/4wt pct SiC composites with different reinforcement sizes have been explained in the authors' previous work. [16] All four UFG materials were annealed to understand the effect of reinforcement particle size, precipitation, grain growth, and PSN on thermal stability during annealing. The annealing treatment was carried out at temperatures ranging from 423 K to 573 K for a time duration of 1 hour followed by water quenching.…”

“…[15] The density of dislocation changes with a reduction in reinforcement particle size. [16] The dislocation structures are even highly thermally unstable compared to the grain structures developed by various SPD techniques. [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] Therefore, the thermal stability of UFG composite materials developed by any SPD process should be thoroughly examined before considering them for any engineering application.…”

“…The details of manufacturing routes are established in the current authors' recent research communication. [16] As per the authors' knowledge, no publications are available to date on the thermal stability of bulk UFG composites (with varying reinforcement sizes) fabricated by cryorolling-based manufacturing routes. Therefore, the thermal stability study of UFG composites with varying reinforcement size via cryorolling is of prime interest.…”

Bulk ultrafine-grained (UFG) AA6063/4wt pct SiC composites with varying reinforcement sizes [12 lm (coarse), 1 lm (fine), and 45 nm (nano)] have been developed by a hybrid route of stir-casting and cryorolling. In the current study, the influence of annealing temperatures (423 K to 573 K) on the precipitation evolution, particle-stimulated nucleation (PSN), recrystallization, grain growth kinetics, and thermal stability of developed bulk UFG composites have been studied, and the resultant effect of microstructural evolution is correlated with mechanical properties. UFG coarse and UFG fine composites have shown evidence of recrystallized grains via PSN and retained their UFG microstructure up to 473 K and 523 K, respectively. Superior microstructural stability with retained UFG microstructure up to 573 K was observed in the UFG nanocomposite due to the effective pinning of nano-SiC particles and precipitates along grain boundaries. This ultimately resulted in the increased grain growth activation energy and strength of the UFG nanocomposite. However, the overall increase in strength is maximum in the UFG nanocomposite due to the dominant effect of dislocation strengthening, grain boundary strengthening, and precipitation strengthening mechanisms. A thorough examination of the microstructural evolution of UFG composites at different annealing temperatures along with their mechanical behavior is presented in this paper.

The natural design and coupling of biological structures are the root of realizing the high strength, toughness, and unique functional properties of biomaterials. Advanced architecture design is applied to many materials, including metal materials, inorganic nonmetallic materials, polymer materials, and so on. To improve the performance of advanced materials, the designed architecture can be enhanced by bionics of biological structure, optimization of structural parameters, and coupling of multiple types of structures. Herein, the progress of structural materials is reviewed, the strengthening mechanisms of different types of structures are highlighted, and the impact of architecture design on the performance of advanced materials is discussed. Architecture design can improve the properties of materials at the micro level, such as mechanical, electrical, and thermal conductivity. The synergistic effect of structure makes traditional materials move toward advanced functional materials, thus enriching the macroproperties of materials. Finally, the challenges and opportunities of structural innovation of advanced materials in improving material properties are discussed.
