Summary: Novel glassy Co-Fe-Ta-Si-C alloys were prepared by mechanical alloying and the effects of annealing treatment and Fe substitution for Co on glass-forming ability, thermal stability, and magnetic properties were investigated. The new Co50Fe25Ta5Si5C15 powders exhibited enhanced glass formation rate and increased GFA compared to the Fe-free Co75Ta5Si5C15 alloy. Thermal analysis revealed high thermal stability and a wide supercooled liquid region for the Co75Fe25Ta5Si5C15 glassy alloy, with improved soft magnetic behavior after milling and annealing treatment.

Summary: Semiconductive ceramic nanoparticles have been studied for their photocatalytic behaviors and can produce radical species even in dark conditions. In this study, it was demonstrated that these ceramic powders, in the form of microparticles, could be used as photoinitiators to synthesize a hydrogel matrix for implantable devices. The ceramic particles are capable of neutralizing radical species in physiological media, while the hydrogel matrix regulates the exchange of free radicals.

Summary: In this study, carbon fibers reinforced SiCN ceramic matrix composites (C/SiCN) were prepared using homemade polysilazanes (PSN-T03) via PIP. It was found that SiCN ceramics began to lose weight at 1400 degrees C, leading to a collapse in the mechanical properties of C/SiCN composites above this temperature.

Summary: In this paper, surface modification of materials using mechanical alloying and electron beam irradiation is investigated. The results show that the Sn-rich Ni-Sn alloy layer obtained through this method has a higher surface hardness compared to the initial pure nickel layer. The atomic structure of the Sn-doped nickel substrate in the alloy layer is also simulated to understand the improvement mechanism.

Summary: Many studies have shown that carbon nanotubes (CNTs) can significantly strengthen pure aluminum and this study investigates whether the same strengthening effect can be achieved in a high-strength aluminum alloy. The results showed that while both composites had the same tensile strength, CNTs had a stronger reinforcing effect in pure aluminum than in the aluminum alloy, suggesting the influence of the matrix on the strengthening behavior of CNTs in aluminum matrix composites.

Summary: The main aim of this study was to produce in-situ alpha-Ti/TiO2/TiC hybrid composites from CP-Ti powders through mechanical milling and spark plasma sintering techniques. The results showed that longer milling time led to the formation of Ti, Ti3O5, TiO, TiO2 phases, and dissolved C atoms from the process control agent. These were then converted to alpha-Ti, TiO2, and TiC phases through spark plasma sintering. The micro-hardness results demonstrated that increasing milling time improved the hardness due to grain refinement and the formation of TiO2/TiC intermetallic particles.

Summary: Surface mechanical alloying with Si powder on Al can create surface composites with improved dielectric properties compared to coarse-grained and annealed Al composites. The composite containing Al-Si solid solution exhibits frequency-dependent behavior for dielectric constant, dielectric loss, and capacitance in a voltage range of 0.1 to 0.5 V at room temperature. Increasing Si content in the surface composite leads to an increase in dielectric constant, tan delta, and capacitance due to the formation of solid solutions between Al and Si. The severe plastic deformed microstructure of the Al electrode plays an important role in controlling the dielectric properties of the Al surface containing Al-Si composite. © 2023 Elsevier B.V.

Summary: The study focused on investigating the wear behavior of a ceramic-metal composite (high Mn steel + 50 wt.% TiC) under different temperatures and atmospheres. A critical temperature of around 125 degrees C was observed, marking a transition in wear mechanisms from hardness dominance to toughness dominance. The competitive micro-mechanisms of surface decarburization and toughening of ceramic particles were delineated, providing interpretation of the wear behavior of ceramic-metal composites.

Summary: The study found that the microwave-sintered La2O3-doped TiB2-Ni powder exhibited the best properties when sintered at 1273 K for 15 minutes. La doping reduced oxygen content, inhibited the formation of brittle Ni3B phase, and improved the mechanical properties of the powder. Therefore, the powder may be a suitable raw material for thermally-sprayed TiB2-Ni coatings.

Summary: Dissimilar transient liquid phase (TLP) bonding of GTD-111 and IN-718 nickel-based superalloys was investigated using BNi-9 as an interlayer at 1100 degrees C. The study showed that the bonding time affects the microstructure and mechanical properties of the TLP-bonded specimens. Micro-hardness investigations revealed a decrease in hardness with the completion of isothermal solidification, while shear strength test results demonstrated an increase in shear strength with incrementing bonding time.

Summary: This study investigates the effects of particle shape on the collapse of granular columns using the discrete element method. The results show that particle shape has a significant impact on deposition morphology, energy evolution, and mechanical coordination number. Sphericity and angularity are identified as the most important macroscale factors, while roughness has a weaker microscale influence.
