Summary: The microstructure and high cycle fatigue property of maraging stainless steels with Ti addition were studied. The crack initiation mechanism in HCF depends on the value of normalized applied stress, where high NAS is controlled by yield strength dominated by nano-size precipitates and low NAS is controlled by the distance between TiN inclusion and specimen surface.

Summary: The mechanical response of TRIP-enabled metastable high entropy alloys is characterized by a constant work hardening segment followed by stages of gradual drop in work hardening under uniaxial tension. A four-parameter empirical model based on this work hardening curve has been developed and offers ease of identification from macroscopic mechanical response. Insights can be drawn from the model parameters when fitted to the tensile deformation response of TRIP HEAs, and a method to predict the tensile mechanical response based on correlated parameters with stacking fault energy and microstructure is proposed.

Summary: The study found that beta-annealed Ti64 alloys with a microstructure of alpha colonies had slightly inferior resistance to High cycle fatigue than those with a basketweave microstructure. However, the fatigue crack propagation rates were lower in the former, especially in the low ΔK regime. Crystallographic crack growth prevailed in the microstructure of alpha colonies, leaving cleavage facets on the fracture surface and less fatigue damage at the crack tip.

Summary: The fatigue behavior of Ti-6Al-4V with a bi-modal microstructure was investigated using different waveforms, load ratios, and frequencies. It was found that cracks were initiated along (0001) twist grain boundaries, which is consistent with prior studies. The results also showed that the critical microstructural configurations were not sensitive to environmental factors, free surfaces, loading conditions, and microstructure and composition.

Summary: A multiscale crack iteration and remeshing model was proposed to predict low-cycle crack propagation behavior in steel. The model quantified crack propagation behavior using fatigue indicator parameters in a crystal plasticity model. An iteration procedure and multiscale simulation method were used to relax the fatigue driving force and obtain boundary conditions. The model was validated through experimental results and showed good agreement with the observed crack behavior.

Summary: Compact tension tests were conducted on TRIP maraging steel with two different annealing times. The results showed that the resistance to long crack growth increased with increasing annealing time, while the resistance to short crack growth decreased. Additionally, increasing the annealing time reduced the yield and tensile strengths of the steel. The major microstructural change caused by increasing annealing time was an increase in the fraction of retained austenite.

Summary: The fatigue crack growth behavior of the TWIP Titanium alloy Ti-5Al-1 V-Sn-1Zr-0.8Mo with different microstructures was studied. The lamellar structure showed higher resistance to fatigue crack growth, while the equiaxed and bimodal structures exhibited lower resistance but higher strength and elongation to failure. The presence of deformation twins (DTs) in the lamellar and equiaxed structures contributed to crack deflection and increased crack path tortuosity, enhancing the resistance to fatigue crack growth.

Summary: In this study, the fatigue behavior of the porous biomaterial Ti6Al4V-6Cu, produced by selective laser melting (SLM) in air and in 0.9 wt% NaCl solution, was experimentally investigated. It was found that crack initiation is accelerated in a state of high stress and crack propagation is accelerated in a solution containing 0.9 wt% NaCl. Moreover, the porous Ti6Al4V-6Cu sample has a higher fatigue strength and longer fatigue life compared to the Ti6Al4V sample.

Summary: Low Young's modulus 8-type titanium alloys, such as the Ti-45Nb alloy, have elastic properties close to that of human bone and contain non-toxic elements, making them highly desirable for load bearing implants. Severe plastic deformation methods, such as high pressure torsion, can significantly increase their relatively low hardness and strength. The fatigue crack growth behavior of Ti-45Nb in different microstructural states (as-received, HPT-deformed, HPT + cold-rolled, HPT + heat-treated) was investigated using compact tension specimens. The alloy exhibited weak anisotropy in the fatigue crack growth behavior, attributed to the transcrystalline fracture mode.

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.
