Summary: After ECAP processing, AA6060 aluminum alloy showed a substantial increase in hardness, with stability improving with the number of passes. Grain size and growth kinetics were affected, and annealing temperature had an impact on material properties and structure, leading to reduced hardness and increased grain size at higher temperatures.

Summary: This study investigates the effect of fiber volume fraction on fiber distribution in steel fiber reinforced self-compacting concrete (SFRSCC) through experiments and numerical simulations. The results show that the distribution state of the fibers on the beam sections is correlated to the fiber volume fraction, with a higher fiber volume fraction resulting in better fiber uniformity but worse fiber alignment. The numerical results also indicate that the distribution law of fibers along the length direction of the specimens is almost independent of the fiber volume fraction.

Summary: The study revealed that the refinement of microstructure in Mg-6Al-1Zn-0.9Sn alloy processed by ECAP is highly dependent on the processing temperature, mainly due to the precipitation of secondary-phase particles. The formation of a 45 degrees texture during the ECAP process significantly influences grain boundary strengthening and yield strength.

Summary: The grain morphology, grain boundary characteristics, and texture compositions of different regions in the 6082-T6 aluminum alloy friction plug welded joints were studied using Electron backscatter diffraction (EBSD). The results revealed that the material at the plug and hole junction underwent thermoplastic deformation, dynamic recovery, and recrystallization, resulting in significant refinement of the joint grains. Moreover, inter-grain misorientation deviated from random distribution to a noticeable preferred orientation.

Summary: The research focuses on analyzing the damage evolution and microstructural fracture mechanisms of dual-phase steels under quasi-static uniaxial and cyclic tensile tests, considering the influence of martensite volume fraction and distribution. Intercritically annealed samples at different temperatures are used to obtain varying martensite volume fractions. Damage evolution is evaluated based on stiffness loss, revealing lower ductility and strength under cyclic loading conditions. The presence of higher martensite volume fractions results in a faster rate of damage evolution. The primary void nucleation mechanisms observed are ferrite-martensite and ferrite-ferrite decohesion, while martensite fracture is activated based on martensite volume fraction and distribution along the ferrite grain boundary. The high dislocation density on grain boundaries is attributed to the austenite-martensite transformation during quenching and subsequent plastic deformations, and is related to stored strain energy, stress concentration, and fracture mechanisms near martensite grains. Nanoindentation is conducted to evaluate the hardness of ferrite and martensite, which is influenced by their carbon content. The martensite/ferrite hardness ratio is found to affect the uniform elongation of the material.

Summary: An ultrafine-grained AZ31 Mg alloy processed through multipass equal channel angular pressing (ECAP) achieved mean grain sizes of 5 and 0.9 μm after two and four passes, respectively. Tensile testing at high temperatures revealed that the four-pass-processed alloy exhibited a superplastic elongation of 410% at 250 degrees C. The deformation behavior was studied using the Haehner criterion, showing that grain boundary sliding was the rate-controlling mechanism with a strain rate sensitivity of 0.38. The contribution of slip system to superplasticity was discussed using Schmid factors, which showed that slip activity prevalence at high strains induced texture-strengthening effect and low-angle grain boundary formation.

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 study proposes a novel strategy for achieving the bonding of SiC ceramic and Al alloy using ultrasound. The ultrasound promotes the dissolution of Al into the solder, activating the solder and triggering the interfacial reaction between SiC ceramic and solder. With increasing ultrasonic duration, the bonding between SiC and Al transitions from partial to full metallurgical bonding.

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.
