Summary: This study explores the potential of ECMAE in improving the mechanical properties and thermal stability of PLA, with better effects observed in linear PLA. Simple shear deformation in ECMAE leads to improved crystallinity and the formation of alpha crystals, resulting in enhanced performance of the material.

Summary: The reactive compounding of phenolic OH-functionalized polycarbonate (PC) with epoxy-functionalized polymethylmethacrylate (PMMA) was investigated. It was found that the PC/PMMA copolymer formed during the melt reaction and its presence affected the optical and mechanical properties of the blends. Transparent PC/PMMA blends with two-phase morphologies were obtained, combining high light transmission and excellent mechanical performance.

Summary: In this study, the in-plane Young's moduli E-parallel to of 2D lead halide Ruddlesden-Popper HOIPs were systematically investigated. It was found that E-parallel to generally follows the trend of Pb-X bond strength, showing more prominent effects of the metal halide inorganic framework on E-parallel to than E-perpendicular to. The mechanical anisotropy of 2D HOIPs can be tuned based on structural composition, particularly for iodide-based 2D HOIPs, providing valuable insights for materials design and device optimization.

Summary: Biodegradable films with different weight proportions of thermoplastic starch (TPS) and poly(butylene adipate-co-terephthalate) (PBAT) were prepared. The relationship between the phase morphologies and mechanical properties of TPS/PBAT composite films was investigated. The results showed that the mechanical properties were correlated with the continuity indices of the two phases, with a positive correlation with the continuity index of PBAT and a negative correlation with that of TPS.

Summary: Three-dimensional structures were constructed during the fabrication process of glass-fiber-reinforced thermosetting cyanate ester/bismaleimide composites. A self-stitching technique was developed to aid in the crack self-healing of the composites. The mechanical properties of the composites were significantly improved by the 3D structures. The healing efficiency of the composites reached 96%.

Summary: Porous alumina was prepared using sacrificial template approach with different pore formers. The pore structure and pore size of the porous alumina were influenced by the volume content and shape of the pore formers. The porosity and pore size of the alumina increased with the increase in carbon fiber content. The surface fractal dimension decreased with the increase in pore former content.

Summary: A novel non-equiatomic high entropy alloy (HEA) Al15.85Fe11.15Co32.11Cr10.76Ni30.13 was fabricated using a powder metallurgy method. The HEA exhibits a dual-phase microstructure consisting of face-centered-cubic (FCC) and body-center cubic (BCC) phases. It possesses high compressive yield strength, fracture strength, fracture strain, and strength at high temperature due to the uniform dispersion of L12 and B2 nanoprecipitates in the FCC and BCC phases, respectively. This finding provides guidance for the development of high-performance structural materials with a balance of strength and ductility for industrial applications.

Summary: This study systematically investigates the microstructure evolution and mechanical properties of Steel/Mg composites. It is found that there is an interdiffusion phenomenon of Mg and Zn elements at the interface of the composites, forming an interdiffusion layer and compounds. The inclusion of steel wire can effectively reduce the texture strength of the Mg alloy matrix, and the Steel/Mg composites exhibit higher tensile and compressive strength compared to Mg-R. This research provides a novel, time-saving, and cost-effective method for manufacturing continuous fiber reinforced metal matrix composites (CFRMMCs), expanding the application of metal composites.

Summary: The addition of Al and Ca microelements can improve the mechanical properties of magnesium alloys, but Al addition can deteriorate corrosion resistance, while the single addition of Ca can help increase both tensile and compressive yield strengths and improve yield anisotropy. This property improvement was achieved without compromising corrosion resistance. A ViscoPlastic Self-Consistent simulation showed that the single Ca addition effectively enhanced the hardening of basal and prismatic slips, resulting in improved yield strength in both tension and compression.

Summary: The study showed that as the water soaking time increased, the pore sizes in coal expanded and new pores developed, leading to changes in mineral composition and structural characteristics. The mechanical properties and ultrasonic wave velocity of coal decreased with increasing water-soaking time, and could be expressed by exponential functions.

Summary: This study investigated the effects of Ga content on the microstructure and mechanical properties of hot-extruded Mg-2Zn-xGa alloys. The results showed that increasing Ga content refined the grains and increased the amount of Mg5Ga2 precipitates, leading to enhanced strength properties. However, excessive Mg5Ga2 precipitates resulted in reduced elongation.
