Summary: Surface modified CNTs were hybridized with in situ Mg2Si nanoparticles through chemical oxidization to enhance the synergistic strengthening in Mg matrix composites. The tailored volume ratios of CNTs to Mg2Sip using powder thixoforming technology resulted in improved mechanical properties. The strengthening effects of the CNTs-Mg2Sip reinforcements were more effective than using individual CNTs or Mg2Si nanoparticles.

Summary: In this study, the uniform distribution of Ni-coated CNTs in the matrix was achieved by optimizing the content of CNTs. It was found that when the CNT content is less than 1%, the CNTs can be evenly distributed in CNT/Mg composites, resulting in a significant increase in strength. Furthermore, the coated Ni in the CNTs reacts with the magnesium matrix and completely transforms into Mg2Ni, significantly enhancing the interface bonding.

Summary: B4C/Al composites with 30 wt% B4C content were successfully fabricated by hot pressing sintering and hot rolling. The influence of hot rolling on the microstructure, mechanical properties, anisotropy, and interfacial conditions of the composites was investigated. The results showed that hot rolling improved the distribution of Al2O3 nanoparticles at the interface, leading to increased strength and ductility of the composites. Additionally, the dispersion of Al2O3 nanoparticles into the Al grain interior contributed to the strengthening and toughening mechanisms through Orowan strengthening and enhancement of dislocation storage ability.

Summary: In this work, high-quality boron nitride nanotubes (BNNTs) and carbon nanotubes (CNTs) were synthesized, and well-dispersed BNNTs/Cu and CNTs/Cu composites were successfully prepared. The mechanical properties and strengthening mechanisms of these composites were compared and discussed in details. The results showed that both BNNTs/Cu and CNTs/Cu composites exhibited improved ultimate tensile strength (UTS) compared to pure Cu, with BNNTs/Cu outperforming CNTs/Cu at high temperatures due to stronger inter-walls shear resistance and higher thermomechanical stability.

Summary: In this study, in-situ scanning electron microscopy microcompression tests were conducted on bcc Fe micropillars to investigate their plastic behavior under different strain rates. Different plastic mechanisms were identified based on their inherent frequencies, with dislocation avalanches occurring at 3 Hz at low strain rates and solute-driven instabilities occurring at around 10 Hz. At high strain rates, the frequencies of these mechanisms overlapped, around 100 Hz, indicating a complex interaction between them. These findings are in agreement with a DSA behavior controlled by interstitial impurities such as C, N, and O and their interaction with dislocations.

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: Cold-rolled pure titanium showed improved sheet formability after undergoing cryogenic-deformation treatment. This treatment increased the thinning capability of the titanium and suppressed cracking during sheet forming. The formation of twins during deformation contributed to high thinning capability and increased strength through grain refinement and dislocation accumulation.

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.
