Summary: A warm equal-channel angular pressing (ECAP) procedure was applied to investigate the microstructure, superplasticity, and deformation mechanism of a Mg-6.5Y-1.2Er-1.6Zn (WEZ612)-0.5Ag alloy. The alloy exhibited remarkable elongation of 726% at 623 K and a strain rate of 0.01 s-1, with the primary deformation mechanism being grain boundary sliding assisted by lattice diffusion. This improvement in superplasticity was attributed to the presence of stable LPSO phases, g precipitates, and nano-precipitates, which hindered crack propagation and grain growth and promoted basal plane slip.

Summary: Shear punch testing was used to evaluate the superplasticity of a hot rolled fine-grained Mg-3Zn-0.5RE-0.5Zr (ZEK300) alloy. The alloy exhibited regions I, II, and III of deformation behavior typical of superplastic materials, with a grain size of 4.5 μm. In region II, the strain rate sensitivity indices of the ZEK300 alloy were determined to be 0.51, 0.48, and 0.41 at temperatures of 350, 400, and 450 degrees C, respectively. The average activation energy of 87.6 kJ mol-1 suggests that grain boundary sliding (GBS) facilitated by grain boundary diffusion is the dominant deformation mechanism.

Summary: The influence of B on the superplasticity of Fe-6.6Mn-2.0Al alloy was studied using high-temperature tensile testing. The addition of B increased peak stress and apparent activation energy, while decreasing strain rate sensitivity, affecting grain size and phase fraction. The increase in elongation with B addition may be attributed to the finer grains achieved by suppressing dynamic grain growth.

Summary: ZK60 magnesium alloy is refined through submerged friction stir processing (SFSP), leading to the observation of high-strain-rate superplasticity (HSRS) at elevated temperature. The excellent HSRS is attributed to the uniform fine-grained structure and the relatively high fraction of high-angle grain boundaries, which facilitate grain boundary sliding. Additionally, the presence of dispersed fine particles/precipitates enhances the microstructural stability of the specimens.

Summary: Experimental studies have revealed that many cavities are formed at grain boundaries and grain boundary triple junctions of fine-grained magnesium specimens during plastic deformation at room temperature, and the size and density of these cavities increase with the progression of deformation. The majority of cavities are controlled by plasticity, and their growth rate is similar to those observed in superplastic magnesium alloys tested at elevated temperatures.

Summary: This study investigates the micromechanics of superplastic deformation of Zr-2.5 wt.%Nb alloy using EBSD analysis. The results show that the superplastic flow at 700 degrees C is accommodated by Rachinger grain boundary sliding and co-rotation of alpha/beta grains. Texture weakening in alpha and beta-Zr phases is observed and is not caused by slip-based deformation. The fraction of interfaces between alpha and beta phases remains unaffected during the superplastic flow.

Summary: This study systematically investigated the tensile creep of 3 mol% Y2O3 stabilized tetragonal ZrO2 ceramics under a DC field. The results showed that the deformation mechanism of the material strongly depended on the current density and applied stress. Exceptionally large uniform elongation can be obtained when the creep is dominated by dislocation accommodated grain-boundary sliding.

Summary: During superplastic deformation of microduplex-structured brasses, strain primarily occurs in the beta-phase through grain boundary sliding and dislocation slip/creep mechanisms. Dynamic recrystallization and twinning transform the initial coarse beta-phase grains into ultrafine grains, and alloying with Al improves superplastic behavior and reduces residual cavitation.

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: The deformation behavior of Ti-22Al-25Nb alloys with refined initial grain size was studied, revealing significant continuous flow softening at low to moderate strain rates. Analysis of the microstructures using EBSD showed the presence of grain boundary sliding (GBS) mechanism in addition to conventional mechanisms. The study provides direct evidence of GBS in current alloys and identifies its dominant role in high-temperature deformation and softening.

Summary: The grain size and grain boundary density have significant effects on the flow stress of metallic materials. The Hall-Petch grain refinement strengthening effect, which is a linear relationship to the inverse of the square root of the grain size, has been well-established for more than 70 years. However, grain refinement softening can occur at high homologous temperatures and both effects have been treated separately. Recent research has shown that a general relationship can explain both the Hall-Petch strengthening effect at low temperatures and superplasticity at high temperatures. This review discusses recent advances in structural and mechanical characterization and provides an updated analysis of the relationship between grain size and flow stress.

Summary: Addition of Al to equiatomic high entropy alloy promotes formation of BCC phase and sigma phase. Straining by caliber rolling induces morphological changes related to planar faults, where sigma phase nucleates first on the matrix faults followed by formation of B2 phase driven by elemental concentration changes. This study provides insights into the formation mechanisms of different phases in the alloy.

Summary: Biodegradable magnesium-based composites have gained attention due to their biocompatibility and the ability to modify their mechanical and corrosion properties. This study investigated the effects of the fraction and crystal structure of tricalcium phosphate (TCP) on the electrochemical and mechanical properties of Mg-Ca/TCP composites. High-strength composites with a fine-grained matrix were prepared and exhibited compressive yield strengths exceeding 290 MPa. The electrochemical tests showed that the corrosion parameters were not affected by the fraction and crystal structure of TCP particles.

Summary: This study investigated the influence of parent austenite grain refinement on the intervariant boundary network in a lath martensitic steel. It found that refining the parent austenite grain led to a decrease in the fraction of certain boundaries in the martensite and an increase in the connectivity of low energy boundaries, ultimately improving the impact toughness.

Summary: Metastable beta Ti alloys based on the Ti-Nb system have attracted attention due to their unique properties. However, the unstable cyclic behavior of these alloys has hindered their widespread industrial use. Recent studies have shown that internal stresses, including those from dislocations, may be responsible for this behavior. This study demonstrates that inter-cycle thermal treatments can mitigate the unstable cyclic behavior, providing a significant breakthrough in our understanding of Ti-Nb superelastic materials.

Summary: This paper systematically investigated the evolution of microstructure in Fe-Ni-Co-Al polycrystalline alloys and its effects on mechanical properties. The results revealed that the migration of grain boundaries in different processes is driven by different factors, which impacts the grain orientation and precipitate formation. In the process of directional recrystallization, grains with specific orientations grow in the grain boundary region and form the dominant orientation, while grains with lower migration rate form the minor orientation. The alloy produced through directional recrystallization exhibited good recoverable strain and superelastic strain, while the alloy produced through solid solution treatment showed no evident superelastic behavior.

Summary: This study employed laser metal deposition to additively manufacture Ti-15Mo wt% alloy, and subsequently subjected it to post-fabrication uniaxial thermomechanical processing. The results showed that different zones in the microstructure remained after processing, and deformation mechanisms mainly involved slip and martensite formation. The compressive mechanical properties were found to be dependent on strain rate, with higher flow stress and compressive strength observed at higher strain rates. Grain structure homogenisation was not achieved, leading to anisotropic tensile properties.

Summary: This research aims to investigate the effect of roughing and finishing reductions on crystallographic texture. The results show significant heterogeneity in the centerline region, with higher intensity of certain textures. Drop Weight Tear Test indicates that steel specimens with lower and medium reductions exhibit superior low-temperature impact toughness compared to steel with higher reductions. The electrochemical hydrogen charging experiments confirm the presence of internal hydrogen cracks only in steel with lower and medium reductions.

Summary: This study examines the effect of Cr additions on the mechanical behavior of TWIP steel at temperatures ranging from 25°C to 350°C. The results indicate that different temperature-dependent strengthening mechanisms, including mechanical twinning, Dynamic Strain Aging, and slip bands, are at play. The stacking fault energy (SFE) influences the percentage of mechanical twinning, which in turn affects the strain hardening rate.

Summary: This study explores the weldability, microstructures, and mechanical properties of two L1(2)-nanoparticle-strengthened medium-entropy alloys after electron beam welding (EBW). The results show that strong yet ductile defect-free joints were produced, with larger grain sizes in the fusion zones compared to the heat-affected zones and base materials. Both EBWed MEAs exhibited high yield strengths, high ultimate tensile strengths, and good fracture strains at 77 K. The V-doping improved the cryogenic mechanical properties of the TMT MEA.

Summary: The mechanical properties and microstructural evolution of C-doped TRIP-assisted HEA under dynamic loading conditions were systematically investigated in this study. The results showed that dynamic tensile deformation led to an increase in yield strength and a decrease in ultimate tensile strength, with a trend towards increased total elongation. The primary deformation mechanisms shifted from TRIP and TWIP effects to deformation twinning and dislocations. The presence of carbides formed through C-doping hindered dislocation slip and promoted the activation of multiple twinning systems.
