Summary: The mechanical and tribological characteristics of PEEK sheets were improved by electron beam irradiation. The lowest specific wear rate was achieved by PEEK sheets irradiated at a speed of 0.8 m/min with a total dose of 200 kGy. The improvement in microhardness was observed in samples exposed to an electron beam at a speed of 9 m/min for 30 runs with a total dose of 300 kGy.

Summary: This study focused on providing an alternative material for cylinder liners of automotive and aircraft engines, by utilizing friction stir processing on AA7075 with different weight ratios of Al(2)O(3) and SiC reinforcements. The addition of 3.7 wt.% Al2O3 + 3.0 wt.% SiC in AA7075 enhanced the microhardness about 33.96% higher than the base matrix, leading to improved wear resistance. The dry sliding wear behavior analysis showed that increasing the weight percentage of Al(2)O(3) particles enhanced the wear resistance of AA7075 surface hybrid composites, particularly at higher loads, due to the formation of protective tribofilm.

Summary: In this study, wear resistant coatings, including hydroxyapatite (HAp) and reduced graphene oxide (rGO), were applied to polyetheretherketone (PEEK) sample through dip coating method. It was found that adding rGO enhanced the friction and wear resistance of the coating, with HAp+rGO composite achieving the best wear resistance. Furthermore, rGO acted as an interstitial bonding agent between PEEK and HAp, increasing bond strength.

Summary: This paper investigates the fabrication of biomimetic textures on CoCrMo artificial knee joints and their impact on friction performance. The results show that the textured joints exhibit better friction properties compared to non-textured joints, and samples with a scaly textured structure show the best friction performances. The mechanisms responsible for this enhancement are explained as micro-textures storing wear debris and lubricating fluid, as well as derivative-cutting behavior removing wear debris.

Summary: Solid lubricants are attracting attention for their use in special working conditions, and MXenes have become popular due to their nanolaminated structure and weak interactions. The MXene-based films modified with polydopamine showed significantly enhanced tribological performance and load capacity, with Si-MX/PDA-HOAC performing the best. A lubricating protection film containing FeF2 formed on the silicon/steel surfaces played a key role in demonstrating excellent tribological properties in this study.

Summary: The present study focuses on improving the microhardness and wear properties of AISI 1020 steel by depositing TiB2-Fe composite coating using tungsten inert gas (TIG) cladding. The microhardness of the coating was found to be influenced by the composition of the coating materials and the TIG processing current. The maximum microhardness was achieved with a composition ratio of 100TiB2-0Fe and a processing current of 90 A. The wear rate of the coating was significantly lower compared to AISI 1020 mild steel, showing improved wear properties.

Summary: In this study, PEEK/PTFE composites reinforced with CFs and Gr were fabricated and their friction and wear properties were investigated. It was found that the introduction of CFs significantly improved the tribological properties, but the addition of CFs alone resulted in higher friction coefficient. However, a combination of CFs and Gr showed a synergistic effect in improving the friction-reducing and anti-wear abilities of the composites. The mechanisms behind the improved tribological properties were discussed based on the analysis of the worn surfaces and tribofilms.

Summary: A novel set of Al2O3-B2O3-CaO composites were manufactured using cold press-sintering. The effects of B2O3 content and relative humidity on the properties of the composites were investigated. The in-situ formed aluminum borate enhanced micro-hardness and wear resistance, while the humidity-sensitive alumina phase reduced friction. Addition of CaO improved relative density, hardness, and wear resistance.

Summary: This study investigated the influence of parent austenite grain refinement on the intervariant boundary network in a lath martensitic steel. It found that refining the parent austenite grain led to a decrease in the fraction of certain boundaries in the martensite and an increase in the connectivity of low energy boundaries, ultimately improving the impact toughness.

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 study proposes a novel strategy for achieving the bonding of SiC ceramic and Al alloy using ultrasound. The ultrasound promotes the dissolution of Al into the solder, activating the solder and triggering the interfacial reaction between SiC ceramic and solder. With increasing ultrasonic duration, the bonding between SiC and Al transitions from partial to full metallurgical bonding.

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.

Summary: This research aims to investigate the effect of roughing and finishing reductions on crystallographic texture. 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: This study examines the effect of Cr additions on the mechanical behavior of TWIP steel at temperatures ranging from 25°C to 350°C. The results indicate that different temperature-dependent strengthening mechanisms, including mechanical twinning, Dynamic Strain Aging, and slip bands, are at play. The stacking fault energy (SFE) influences the percentage of mechanical twinning, which in turn affects the strain hardening rate.

Summary: This study explores the weldability, microstructures, and mechanical properties of two L1(2)-nanoparticle-strengthened medium-entropy alloys after electron beam welding (EBW). The results show that strong yet ductile defect-free joints were produced, with larger grain sizes in the fusion zones compared to the heat-affected zones and base materials. Both EBWed MEAs exhibited high yield strengths, high ultimate tensile strengths, and good fracture strains at 77 K. The V-doping improved the cryogenic mechanical properties of the TMT MEA.

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.
