Summary: In order to improve the flammability and brittleness issues of epoxy resin (EP), a series of hyper-branched benzoxazines (HB1.0-HB2.5) were synthesized using DOPO-2OH and Jeffamine T403. The results showed that HB2.0 with the optimized hard/soft segment ratio was the most effective additive for EP. The EP/HB2.0 system exhibited enhanced performance with a 115% increase in impact strength and 5.7 degrees C higher Tg compared to the pristine EP. Impressively, even at a low loading of HB2.0, the modified EP achieved a UL-94 V-0 rating and a LOI value of 30.8%, indicating improved flame retardancy.

Summary: Epoxy foams with densities ranging from 180 to 500 kg/m3 were mechanically tested and a transition in fracture behavior at a critical density was observed. Lower density foams exhibited lower toughness and fracture energy, while higher density foams showed higher values. Stress-intensity factor increased monotonically with density. The distribution of cell size varied between lower and higher density foams. This study suggests the potential use of higher density foams in composite sandwich structures to achieve increased fracture energy.

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.

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: 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.
