Summary: This paper presents a blind benchmark of seven different models applied to two virtual materials for prediction of longitudinal tensile failure of unidirectional composites. Capturing the localization of stress concentrations was vital in predicting the effect of matrix stiffness and strength on composite failure strain and strength as well as fiber break and cluster development. The discussions provide insight into how model assumptions are linked to the differences in predictions.

Summary: Graphene oxide (GO) was used as a coupling agent between the epoxy matrix and flax fiber in flax/epoxy composites, leading to significant improvements in tensile and flexural strength. The presence of GO reduced the total crack length and decreased the rate of cracks at the fiber-matrix interface, resulting in reduced composite failures. The use of GO also enhanced the impact resistance and reduced catastrophic damages in the nanocomposites.

Summary: Delignified wood (DW) offers a versatile platform for manufacturing composites with a wide range of material properties. This study presents a method for fabricating anisotropic and mechanically tunable DW-hydrogel composites. The mechanical properties of these composites can be adjusted by crosslinking time and diffusion-led crosslinking allows for the manufacturing of mechanically graded structures. The resulting anisotropic DW-hydrogel composite enables cell alignment in vitro, which has potential applications in tissue engineering.

Summary: This study compares the mechanical behavior and microstructural characteristics of Cu matrix hybrid composites reinforced with SiC-Gr(p) and WC-Gr(p) fabricated through the stir casting process. The dispersion of reinforced particles in the composites was uniform, and the presence of SiC, WC, and Cu alloy was confirmed by XRD. The addition of hard ceramic materials improved the tensile behavior and microhardness of the Cu-based MMCs, with the WC-Gr reinforced composites exhibiting superior mechanical properties compared to the SiC-Gr reinforced composites. The fracture surfaces indicated ductile fracture in both hybrid composites.

Summary: Good interfacial adhesion is crucial for the performance of composite materials. The interfacial bonding effect of UHMWPE-fiber/LDPE-matrix (LU) and PET-fiber/LDPE-matrix (LP) composites was investigated. LU showed a significantly higher interfacial shear strength (IFSS) compared to LP, resulting in higher tensile strength. The presence of UHMWPE-fiber improved the orientation and crystallization of LDPE molecular chains, leading to the formation of an obvious interfacial transition zone. These findings provide guidelines for the design and manufacturing of high-performance fiber-polymer composites.

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.
