Summary: A reliable solid diffusion bonding between 90 W-7Ni-3Cu tungsten alloy and 304 stainless steel was achieved by using a pure Cu interlayer. The interfaces bonded excellently through mutual diffusion of atoms, without formation of intermetallic compounds or brittle phases. The joint with a Cu interlayer exhibited enhanced tensile strength of 265 MPa, about 58% higher than the joint without a Cu interlayer. Fracture analysis revealed a mixed fracture mode of plastic fracture and intergranular fracture in the Cu interlayer and at the Cu/304SS interface.

Summary: Diffusion welding of CoCrFeNiCu HEA with 304 stainless steel was studied through SEM, EBSD, TEM, and XRD, showing that element diffusion can achieve a high-quality connection between the two metals. As temperature increases, diffusion capacity increases, resulting in disappearance of pores at the interface, with a diffusion layer thickness ranging from 10-31 μm and without forming intermetallic compounds.

Summary: The microstructure and microtexture evolutions of a commercial duplex stainless steel after severe cold rolling at room temperature were investigated. The results showed that both constituent phases were severely deformed and the plastic strain was preferentially partitioned into the austenite phase. As the deformation strain increased, the twin-matrix lamellae gradually rotated and localized shear deformation led to the formation of eye shaped domains composed of nanotwins/fragmented fine structures. Cold rolling significantly improved the strength of the duplex stainless steel but sacrificed its ductility.

Summary: Materials with designed gradient nanograins show exceptional mechanical properties, such as superior strength and ductility. This study demonstrates that a heterostructured 304 stainless steel with solely gradient dislocation structure (GDS) exhibits substantially improved yield strength with slightly reduced uniform elongation compared to its coarse grained counterparts. Microstructural observations reveal that multiple deformation mechanisms, including the formation of dense dislocation patterns, deformation twins and martensitic phase, contribute to the delocalized plastic deformation and superior mechanical performance of the GDS 304 stainless steel.

Summary: This study focuses on the analysis of wear resistance against micro-scratching in metallic coatings. 316L stainless steel powders were deposited onto low carbon steel S355J2 using cold spray, with variations in the pressure and temperature of the propellant gas. Nanoindentation tests were conducted to determine hardness and elastic modulus, microscratch tests were used to measure wear rates and friction coefficients, and scanning electron microscopy was used to analyze the wear mechanisms by evaluating scratch grooves. The relationship between hardness and wear rate was also determined.

Summary: The impact of annealing time on the microstructure and mechanical properties of AISI 310S stable austenitic stainless steel subjected to 90% cryorolling was investigated. After cryorolling, the grain size of the steel was refined to the nanometer level. With increasing annealing time, the degree of grain recrystallization increased, leading to the growth and stabilization of the grain. The strength and hardness decreased, while elongation increased with longer annealing time.

Summary: In this study, Ti-Si-C composite coatings were prepared by plasma spraying and annealed in an Ar atmosphere. The post-annealing treatment did not alter the phase structure but led to increased peak intensity of Ti3SiC2, reduced porosities, and more uniform microstructure in the coatings. The annealed coatings exhibited improved microhardness and fracture toughness, attributed to the uniform microstructure and toughening effect of closed micro-cracks.

Summary: This study investigates the effect of surface roughness on cold-sprayed nickel coatings. The results show that surface preparation significantly affects coating adhesion and microstructure. Coatings deposited at high temperatures exhibit a dense microstructure and good adhesion. Increasing temperature results in thicker coatings and enhances microhardness, nanohardness, elastic modulus, and adhesion. There is no distinct dependence of surface roughness and thickness on the mechanical properties of the coatings.

Summary: The effect of annealing temperature on the microstructure, mechanical properties, and anti-corrosion behavior of X2CrNi12 ferritic stainless steel was investigated. Increasing annealing temperature prevents the precipitation of (Fe, Cr)(23)C-6, leading to improved mechanical properties but decreased elongation. The steel annealed at 770 degrees C exhibits the best corrosion resistance.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.

Summary: This study investigates the effects of high energy/fluence proton radiation on the performance of HfZrOx-based FeFETs memory with different Zr content. The results show that the characteristics of FeFETs are influenced by proton radiation, and the extent of the influence depends on the Zr content. FeFETs with 50% Zr content exhibit minimal changes in memory window and demonstrate good endurance and retention performance.

Summary: In the study of BM-SCO and HSCO thin films, it was found that H vacancies tend to prefer sites near the external surface or oxygen vacancy channels (OVCs), while H interstitials prefer sites of oxygen on a layer that contains six-fold coordinated Co. These findings not only enrich the understanding of complex surface phenomena of defect formation but also provide an explanation for the reversibility during phase transformation.

Summary: In this study, a potential platform to enhance Raman scattering and increase the number of observable Raman modes in monolayer transition metal dichalcogenides (TMDs) was proposed. The platform consisted of large-scale arrays of gold micropillars (MPs), which were able to enhance the Raman intensity of TMDs and make difficult-to-detect Raman modes observable. The platform showed great industrial advantages and wide applicability due to its low cost, simple process, large controllable area, and short process time.
