Summary: Magnesium alloys are appealing for automotive and aerospace applications due to their low density and high strength-to-weight ratio. However, their current use is limited by low strength and poor formability at ambient temperatures. Two-phase nanostructured materials offer a promising solution to enhance the mechanical properties of magnesium alloys, with either fibrous or lamellar morphologies formed via eutectic transformation. During mechanical testing, the lamellar morphology showed superior strength and plasticity compared to the fibrous morphology and pure magnesium. The higher strength in the fibrous eutectic came at the expense of lower plasticity, while the high plasticity of the lamellar morphology was attributed to factors such as high dislocation activity and role of alpha layers in restricting shear instabilities.

Summary: The study investigated dislocation structures in CuNiCoFeCrAl0.3 alloy particles using a transmission electron microscope (TEM). A non-equiatomic CoCrFeCuNiAl0.3 high-entropy alloy composite (HEAC) reinforced with TiC5vol% nanoparticles was produced. X-ray and TEM analyses confirmed a nanotwinned single-phase face-centered cubic (FCC) solid solution with TiC nanoparticles. Further findings showed that formation of twin structures in FCC high-entropy alloys (HEAs) by powder metallurgy technology depended on dislocations and the stratified structure during mechanical alloying. The TiC5vol %CoCrFeCuNiAl0.3 HEAC exhibited excellent mechanical properties including high yield strength, fracture strength, and plastic strain due to dislocation glide, semi-twin expansion, TiC particles, and transgranular twins.

Summary: In this study, (TiC+TiB2)/Al composites fabricated using the Al-Ti-B4C system showed significantly enhanced mechanical properties compared to TiC/Al composites, attributed to the improved interface bonding strength and energy dissipation of crack propagation. The reduction in reaction heat, improved crystallographic match, and enhanced adhesion work between ceramic particles and matrix in the (TiC+TiB2)/Al composites contributed to the formation of enhanced interfaces, providing a new idea for the design and control of interfaces in high-volume-fraction ceramic-metal composites.

Summary: We studied the formation of cross-linked network material through the chains end-group reaction of grafted nanoparticles using molecular dynamics simulation. Our findings suggest that a reaction-limited process is more preferable for fabricating a crosslinked network structure with relatively homogeneous crosslinking points. Additionally, the length of grafted chains plays a crucial role in regulating the distribution of crosslinking points and the mechanical properties of composite materials.

Summary: This study investigates the orientation characteristics of TiC reinforcements before and after thermal deformation and reveals the interface characteristics between the TiC reinforcement and matrix as well as the effects of thermal deformation on TiC particles. The results show that the interface is formed by direct contact between the TiC reinforcement and matrix before thermal deformation, and the interface is clean, flat, and sharp. After thermal deformation, the orientation of the TiC reinforcement becomes random, and the interface characteristics change.

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: 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 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: 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.
