Summary: Superplastic deformation of polycrystalline materials is usually achieved by diffusion-assisted grain boundary sliding at high temperatures. Recent research has shown that room-temperature superplasticity can be achieved in ultrafine-grained Al-Zn based alloys, but the underlying mechanism is still unclear. This study utilized in-situ tensile straining, electron microscopy characterization, and atomistic density functional theory simulation to reveal that the superplasticity at room temperature is achieved by grain boundary sliding and grain rotation, facilitated by the continuous diffusion of Zn. The diffusion of Zn atoms from grains to grain boundaries forms a Zn nanolayer, acting as a solid lubricant to lower the energy barrier of grain boundary sliding.

Summary: Utilizing friction stir processing, an ultrafine-grained structure was achieved in Mg-Zn-Y-Zr alloy leading to extraordinary superplasticity. Grain refinement and homogeneous dispersion of precipitates were promoted by the coupled thermo-mechanical effect, resulting in an ultra-fined grains size of 1.9 +/- 0.4 μm and a superplastic elongation of 642%. Grain boundary sliding was considered as the predominant superplastic deformation mechanism in ultrafine-grained materials.

Summary: Severe plastic deformation is used to refine the grain structure of the Mg-Al-Zn alloy to ultrafine size. Different testing techniques are used to investigate the mechanical behavior and deformation mechanism. The relationship between flow stress and grain size is non-linear in the ultrafine grained range and depends on temperature and strain rate. Experimental observations agree with the deformation mechanism of grain boundary sliding.

Summary: The microstructure evolution and superplastic deformation mechanisms of a 2A97 Al-Cu-Li alloy with initial banded grains were studied. Uniaxial superplastic tensile tests were conducted and surface studies were carried out to investigate the deformation mechanisms. The results showed that the banded grains transformed into equiaxed grains during deformation, and the deformation process could be divided into two stages, with intragranular dislocation slip dominating in the primary stage and grain boundary sliding dominating in the secondary stage.

Summary: After ECAP treatment, Al-Fe alloy shows an increase in the number of pitting corrosion but a decrease in the size of pit corrosion, due to the fragmentation and uniform distribution of precipitated phases. The increase in grain boundary density and the reduction of precipitated phase aggregation also contribute to the decrease in intergranular corrosion. This study provides a new approach to improve the corrosion resistance of Al-Fe alloys by transforming the corrosion mode from local to uniform.

Summary: In this study, an AZ61 Mg alloy was processed by high-pressure torsion (HPT) to refine the grain size. Using a facility with an upscaled capacity of 500 ton, 30 mm diameter disks were processed under 6 GPa. Tensile tests at elevated temperatures showed that the grain size was reduced to around 320 nm after HPT processing at 423 K for 10 turns. This grain size reduction led to a superplastic elongation of more than 400% at 473 K with an initial strain rate of 1.0 x 10(-3) s(-1). Comparing the results with conventional 10 mm diameter disks, it was found that the total elongation was invariably higher for the 30 mm disks, and this difference was attributed to the anisotropy due to material flow.

Summary: The study investigates the low-temperature superplasticity of ultrafine-grained near beta alloy Ti-5Al-5V-5Mo1Cr-1Fe. It demonstrates that the alloy has high relative elongation to failure at a strain rate of 2.10(-3) s(-1), even after annealing at 873K for 1 hour. The preservation of ultrafine-grained structure in the alloy leads to good strength characteristics under conditions of low-temperature superplasticity.

Summary: This study aimed to improve the superplastic ductility of friction-stir welded joints of ultrafine-grained (UFG) Al-Mg-Sc-Zr alloy. The UFG material was produced at elevated temperature to suppress abnormal grain growth, but the new approach resulted in a high fraction of low-angle boundaries, hindering grain-boundary sliding. Thus, superplastic deformation was primarily concentrated in the fully-recrystallized stir zone.

Summary: This study investigates the effect of annealing on the microstructure, precipitation evolution, microhardness, thermal stability, and grain growth kinetics of Al 7075 alloy processed by cryogenic temperature extrusion machining (CT-EM). The study finds that annealing at 150 degrees C improves chip sample hardness through precipitation strengthening. The microstructure contains more dislocation-free equiaxed grains with increasing annealing temperature. The CT-EM method produces a thermally stable ultrafine-grained (UFG) Al 7075 alloy up to 350 degrees C.

Summary: The effect of preliminary precipitation of Al3Sc particles on the superplastic conductor Al-0.5%Mg-X%Sc alloys with ultrafine-grained microstructure was studied. The preliminary annealing was found to weakly affect superplasticity characteristics but promote pore formation and reduce the volume fraction of recrystallized microstructure. Dynamic grain growth was nonuniform, with the maximum recrystallized microstructure observed in regions of plastic deformation.

Summary: In this study, non-uniform Mg solute distribution (i.e., Mg-enriched/depletion zones) around grain boundaries (GBs) in a nanocrystalline Al-8 Mg alloy was observed through experimental observation. The abnormal segregation hindered GB migration and dislocation motion, thus enhancing the strength of the material. A proposed inhomogeneous solute distribution mechanism may contribute to the development of new strengthening mechanisms for nanocrystalline materials.

Summary: This paper analyzes the fracture kinetics and mechanisms of different ultrafine-grained materials with different crystal lattices in the low-cycle fatigue region. The tests conducted show that the formation of ultrafine-grained structure has an unclear effect on the total number of cycles to failure of the samples. The fatigue crack initiation cycles account for about 20% of the total life of the samples, regardless of the material state and crystal lattice type. The fatigue crack propagation rates of the majority of investigated ultrafine-grained materials are close to or lower than that of the initial coarse-grained materials.

Summary: Strengthening and softening mechanisms in ultrafine-grained materials have been debated for many years. This study examines the Hall-Petch relationship in ultrafine-grained magnesium, aluminum, copper, and iron. The results show that while the materials follow the Hall-Petch relationship initially, an up-break occurs for grain sizes below 500-1000 nm. This is due to enhanced dislocation contribution. However, a down-break occurs for grain sizes smaller than 70-150 nm due to diminished dislocation contribution and increased thermally-activated phenomena. The study also finds that strategies other than grain refinement, such as microstructural stabilization by segregation or precipitation, are necessary to achieve extra strengthening.

Summary: This study demonstrates for the first time the influence of high-pressure torsion (HPT) on microstructural refinement and mechanical strength of Ti-6Al-4V titanium alloy produced by wire-feed electron-beam additive manufacturing. HPT processing results in an ultrafine-grained (UFG) structure and significantly increases the microhardness of the alloy. Microscopic studies reveal that the UFG structure consists predominantly of alpha and beta phases.
