Design of pure aluminum laminates with heterostructures for extraordinary strength-ductility synergy

Xiang Chen et al.

Summary: This paper presents the fabrication of sandwich-structured pure aluminum laminates and investigates the mechanical differences resulting from microstructure heterogeneities at the hetero-interface. The annealing process is controlled to obtain a larger degree of heterogeneities, which contribute to higher tensile ductility and strength. The study also reveals the significant strain gradient and the involvement of geometrically necessary dislocations, which contribute to the hetero-deformation induced strengthening and hardening.

Microstructure dependent dislocation density evolution in micro-macro rolled Al2O3/Al laminated composite

Behzad Sadeghi et al.

Summary: In this study, Al2O3/Al laminated composites with high dislocations storage capability were fabricated using flake powder metallurgy combined with micro/macro-rolling. The effect of deformation mode, grain size, aspect ratio, and crystallographic textures on dislocation density was analyzed. The results showed that the dislocation density is influenced by Al2O3 dispersion and bonding, as well as mechanical micro-rolling and macrorolling processes. The MMR process was found to provide laminated ultra-fined grains with higher dislocation storage capability compared to equiaxed grains.

Trimodal grain structure enables high-strength CNT/Al-Cu-Mg composites higher ductility by powder assembly & alloying

Xiaowen Fu et al.

Summary: A novel trimodal grain structure was designed to achieve an excellent strength-ductility combination in CNT/Al-Cu-Mg composites. Tensile tests, in-situ tracking of strain distributions, and computational simulations were used to provide insights into the underlying mechanisms of how the trimodal grain structure enhances the mechanical properties of the composites. The results show that the trimodal grain structure facilitates strain hardening and alleviates strain/stress concentrations, leading to high yield strength and large tensile ductility in the composites.

Summary: Inspired by the design principle of nacre, a bottom-up strategy was employed in the fabrication of bioinspired laminated composites with a brick-and-mortar structure. The composites achieved a significant enhancement in strength with a slight compromise on ductility, leading to improved toughness compared to the corresponding Al matrix.

Enhanced strain hardening by bimodal grain structure in carbon nanotube reinforced Al-Mg composites

Xiaowen Fu et al.

Summary: In this study, bimodal microstructures were prepared in CNT/Al-Mg composites with the weight fraction of coarse grains. The sample with 25 wt% coarse grains showed improved plastic deformation behavior and higher strain hardening ability. The uniform micro-strain distribution in the CG25 sample was attributed to the constrained deformation of soft coarse-grain phase by hard CNT-enriched UFG Al-Mg phase.

Effect of Bimodal Grain Structure on the Microstructural and Mechanical Evolution of Al-Mg/CNTs Composite

Behzad Sadeghi et al.

Summary: The study evaluated Al-Mg alloy structure reinforced with carbon nanotubes, produced through modified flake metallurgy technique and hot extrusion, which exhibited a bimodal microstructure contributing to high strength, uniform elongation, and strain hardening ability. The presence of Mg transformed the native Al2O3 layer into spinel MgAl2O4 nano-phases, improving the interfacial bonding of Al-Al and Al-CNT. The effect of reinforcing phases percentages on dislocations mechanisms evolution was assessed through stress relaxation tests.

Zhiming Zhang et al.

Summary: The bioinspired multiscale Al2O3-rGO/Al laminated composite, prepared by adding hierarchically aligned Al2O3 and rGO nanosheets into Al matrix, shows a synergistic strengthening effect and additional strengthening mechanism attributed to enhanced load transfer due to good bonding at Al2O3/rGO/Al interface. It presents a new strategy for developing advanced composites with simultaneous enhancement of the modulus-strength-ductility.

Modelling of strain rate dependent dislocation behavior of CNT/Al composites based on grain interior/grain boundary affected zone (GI/ GBAZ)

Behzad Sadeghi et al.

Summary: The strain rate dislocation behavior in carbon nanotubes reinforcing aluminum is described through an explicit, analytic grain interior/grain boundary affected zone (GI/GBAZ) composite model. The mechanical behavior of metal matrix composites under different strain rates depends on the different response of dislocation accommodation in GBAZ and GI, which originates from geometrically necessary dislocation (GNDs) and statistically stored dislocation (SSDs). Experiments and simulations clarify that the dominant deformation mechanism of the CNT/Al composite is strain rate dependent, and the GI/GBAZ model successfully reveals the dislocation dependency of strain rate in metal matrix composites reinforced with nanocarbon structures such as CNTs.

Summary: Flake powder metallurgy (FPM) is a new powder metallurgy technology that utilizes flake metal powders obtained by low-speed ball milling to enhance strength and ductility. Control of powder shape is crucial for the preparation of advanced material structures. Future studies should focus on optimizing the processing route of FPM.
