Summary: This study employed hot isostatic pressing to bond directionally solidified and fine equixed grain hybrid structured rods. The results showed that the bonded samples had improved strength after heat treatment, with decreased grain size and volume fraction of carbides and γ-γ' phase. The distribution of nano- or sub-micro-sized carbides within the matrix and grain boundaries inhibited fracture accumulation during tensile tests, resulting in fractures mainly occurring in the directionally solidified piece.

Summary: Additive manufacturing has great potential in manufacturing complex and precise parts, but defects generated during the process limit its applications. This study used ultrasonic fatigue testing to evaluate the effects of sandblasting and hot isostatic pressing on the very high cycle fatigue (VHCF) performance of IN718 fabricated by selective laser melting. Characterization of defects, including size and location, was done using X-ray computed tomography and a 3D-optical profiler. Sandblasting improved the surface state and shifted crack initiation sites from the surface to the interior. With the elimination of defects and the introduction of compressive residual stress, the fatigue resistance was significantly improved.

Summary: The influence of powder particle size on the microstructure of the powder metallurgy superalloy FGH97 was investigated. The results showed that fine powder led to limited plastic deformation, resulting in fewer boundaries and modest particle boundary decoration. On the other hand, medium-sized and coarse powder did not exhibit particle boundary. Therefore, medium-sized powder is the optimal choice.

Summary: This study investigates the precipitation, transformation, and coarsening of carbides in a high-carbon nickel-based superalloy using various microscopic observation techniques and thermodynamic modeling. The results show that a high carbon content leads to the formation of complex carbides, which transform into a different type of carbides and undergo coarsening after treatment. In addition, carbide particles of different sizes are distributed along grain boundaries and subgrain boundaries, and they affect the mechanical properties of the alloy.

Summary: The study showed that the hot workability of a powder metallurgy Ni-based superalloy is influenced by the initial microstructure, with coarse-grained samples having poor hot workability regardless of deformation conditions. In contrast, fine-grained samples exhibited varied hot workability depending on deformation conditions, with a peak observed at the sub-solvus temperature. The presence of prior particle boundaries (PPBs) acted as cavity nucleation sites and crack paths, leading to early fracture and decreased hot workability, especially at lower temperatures and higher strain rates.

Summary: This study demonstrates the feasibility of using a core-shell approach combined with hot isostatic pressing (HIP) to improve the productivity of laser powder bed fusion (LPBF) process for producing Hastelloy-X (HX) components. The core-shell HX with HIP treatment shows a grain size gradient from shell to core, leading to better mechanical properties compared to the HX without the core-shell structure. Moreover, the core-shell approach significantly improves the LPBF production rate.

Summary: Ti-22Al-26Nb and Ti-22Al-26Nb-5B compacts were processed using field assisted hot pressing (FAHP), with differences in processing temperatures and times resulting in varying microstructures. Higher processing temperatures led to fewer pores and three-phase microstructures, while longer processing times resulted in microstructural coarsening. Comparisons were made with compacts consolidated using hot isostatic pressing (HIP), showing finer grain sizes in the B-containing compacts. Compositional analysis suggested the presence of a B27 orthorhombic structure with B2TiNb stoichiometry in the Ti-22Al-26Nb HIP compact.Overall, FAHP was shown to be a viable powder metallurgy processing technique for Ti2AlNb-based intermetallic alloys.

Summary: Piezoelectric silicon carbide (SiC) has been considered for various applications due to its superior properties. However, its brittleness and unsatisfactory piezoelectric response have limited its use. In this study, PVDF/6H-SiC composite fiber films were fabricated and used for assembling high-performance energy harvesters and sensors. The results showed significant improvements in piezoelectric response and sensitivity compared to pure PVDF films. First-principles calculation and finite element analysis confirmed the effect of SiC nanoparticles on the composite film.

Summary: Photocatalytic technology utilizing sunlight as a driving force can convert solar energy into other energy sources for storage and use. CdS, as a typical reducing semiconductor, has attracted attention in photocatalysis due to its suitable bandgap and strong reducing ability. However, the photocatalytic performance of CdS is limited by carrier recombination and photocorrosion. Therefore, CdS has been widely developed as a reducing photocatalyst in constructing S-scheme heterojunctions to overcome these limitations.

Summary: A novel compliant spinal fixation based on compliant mechanisms is designed to effectively reduce stress-shielding effect and adjacent segment degeneration (ASD), but it requires high properties of the used materials. Bulk metallic glasses (BMGs), as young biomaterials, demonstrate excellent comprehensive properties, making them attractive for compliant spinal fixation. In this study, the large deflection deformation behaviors of Zr61Ti2Cu25Al12 (at.%, ZT1) BMG beam were systematically investigated, including elastic, yielding, and plastic deformations. The theoretical nonlinear analytical solution curve predicts the load-deflection relation within the elastic deformation regime and assists in capturing the yielding event, serving as a powerful design tool for engineers. To accurately capture the beginning of the yielding event in biomedical implant applications, the concept of bending proof strength (sigma p,0.05%) with tiny permanent strain of 0.05% was proposed and determined, which is significant for setting the allowable operating limits of the basic flexible elements. The plastic deformation driven by the bending moment can be classified into two stages: the initial stage characterized by nucleation and intense interaction of shear bands, and the second stage dominated by the progressive propagation of shear bands and emergence of shear offsets. The plasticity of BMG beam structures depends on the BMG's inherent plastic zone size (rp), and when the half beam thickness is less than that of rp, the plastic deformation of BMGs behaves in a stable manner, effectively serving as the margin of safety.

Summary: The bainite transformation in medium Mn steels has been experimentally and theoretically studied, and it has been found that the transformation kinetics is slow. However, the introduction of dislocations can significantly accelerate the transformation rate. A new "carbon depletion mechanism" is proposed to explain the role of dislocations in the acceleration of bainite transformation, and a physical model is developed to quantitatively understand the kinetics of bainite transformation.

Summary: Fe-based metallic glasses are promising materials in the fields of advanced magnetism and sensors. This study proposes a novel approach to tailor the amorphous structure through liquid-liquid phase transition, and provides insights into the correlation between structural disorder and magnetic order. The results show that the liquid-liquid phase transition can induce more locally ordered nanodomains, leading to stronger exchange interactions and increased saturation magnetization. The increased local heterogeneity also enhances magnetic anisotropy, resulting in a better stress-impedance effect.

Summary: Metal-organic frameworks derived composites are promising EMW absorbers. Cation substitution can improve their absorption performance by regulating morphology and atomic space occupation. However, the mechanisms of how cation substitution affects EMW absorption performance are still not well understood. In this study, imidazolic MOFs were fabricated and tailored by cation substitution strategy to prepare porous composites. The samples showed optimal reflection loss and effective absorption bandwidth values under low filling rate and thin thickness conditions. The intercoupling between multiple atoms and the porous structure introduced by cation substitution contribute to the improved absorption performance.
