Summary: This study investigated the impact of ultrasonic dispersion on the cavitation effect in magnetorheological polishing fluid (MRPF), revealing that a high volume fraction of solid particles weakens the cavitation effect. It was found that the production of micro-jets is inconvenient when the liquid viscosity is higher. Additionally, the dispersion efficiency and ratio differ between ultrasonic and mechanical dispersion, with experimental results aligning well with simulations and providing a theoretical basis for industrial application of MRPF.

Summary: The application of power ultrasound during the solidification process of Cu-7%Al-4%Ni-2.5%Mn alloy significantly improves nucleation rate, leading to the formation of equiaxed grains with uniform solute distribution and a threefold increase in compressive yield strength. Additionally, the ultrasonic wave enhances the wetting effect between alloy melt and impurities, breaks dendrites into fragments, and promotes symmetrical distribution of temperature, solute, and flow fields in the solidification front.

Summary: In this study, AZ91 magnesium alloys reinforced with hybrid metallic matrix composites consisting of a fixed weight fraction of aluminium oxide (Al2O3: 1.5 wt%) and varying amounts of titanium di-boride (TiB2: 1, 3, and 5 wt%) particles were developed using the stir casting method assisted with ultrasonic agitations. The analysis of the microstructure showed that the monolithic alloy consisted of α-Mg grains with evenly distributed β-Mg17Al12 intermetallic secondary phases near the grain boundaries. Incorporating hybrid reinforcements into the matrix alloy resulted in a decrease in average grain size and a transformation of the β-Mg17Al12 phase from rounded to needle-like profiles. The study of micro-hardness, ultimate tensile strength, and impact strength revealed that the addition of 3 wt% of TiB2 particulates in the AZ91 + 1.5 wt% Al2O3 hybrid composite achieved the highest peak values.

Summary: The study reveals that UPWJ peening has a significant impact on Al-MMC material, increasing both surface roughness and compressive stress. Traverse speed is a key parameter influencing the peening effect, with lower speeds potentially leading to material loss, while the best combination of effects is achieved at a speed of 700 mm/s.

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.
