Summary: The study investigates the properties of Ni-B-GO composite coatings on low carbon steel using pulse electrodeposition, with graphene oxide (GO) as reinforcement. Results show that increasing GO content decreases both the friction coefficient and indentation depth of the coatings, with GO acting as a lubricant during friction and wear tests. The wear mechanism is identified as adhesive wear, and the corrosion potential of the composite coating decreases with higher GO content.

Summary: In this study, different morphologies of microfluidic systems were fabricated on the surface of a Ti3SiC2 ceramic using vapour deposition and fine laser etching. The effects of microfluidics on the microstructure and mechanical properties of the ceramic and Cu brazed joints were investigated. The width of the brazing seam's Ag-Cu eutectic zone varied with the microfluidic morphology, which was attributed to differences in liquid filler wettability. The highest joint strength achieved with microfluidics was 116.9 MPa, which was 15.4% higher than that of joints brazed with smooth ceramics. This work provides theoretical and technical guidance for precision brazing.

Summary: This study successfully lap welded 1.5-mm thick Al-Mg-Li alloy plates using refill friction stir spot welding (RFSSW). The microstructure investigation revealed the occurrence of dynamic recrystallization (DRX) in the stir zone (SZ) of the joint, resulting in fine equiaxed grains. The mechanical properties of the joints were influenced by void defect at the horizontal surface and lack of mixing defect at the vertical interface.

Summary: In this study, equiatomic CoCrFeNi high-entropy alloy was manufactured using solid-state cold spray additive manufacturing technology and then post-spray annealed at temperatures ranging from 500 to 1000 degrees C. Different types of deposits were obtained by adjusting the annealing temperature, and their microstructure and mechanical properties were examined. The as-sprayed deposit showed high compressive yield strength but fractured in the tensile test, indicating tension-compression asymmetry. Recrystallization annealing improved the deposit density and reduced interparticle interfaces, leading to enhanced compressive strength and ductility. Fully recrystallized deposit exhibited weakened tension-compression asymmetry and the best recovery of tensile ductility.

Summary: By using Ti25Zr25Ni25Cu25 amorphous high entropy alloy (HEA) as filler material and combining it with Ag foil, the interfacial microstructure of Ti3SiC2/Cu brazed joint can be regulated to obtain a good joint. The hysteresis effect of the HEA effectively slows down interfacial atomic diffusion and metallurgical reactions, resulting in a relatively thin diffusion reaction zone (DRZ). The combination of Ag foil and HEA ensures a more dispersed and uniform distribution of intermetallic compounds (IMC) in the joint. The maximum shear strength of the joint obtained with the Ti25Zr25Ni25Cu25 and Ag composite filler is 34.85% higher than that obtained with Ag-26.7Cu-4.5Ti conventional filler, and the electrical resistance is 20.35% lower than that obtained with the single Ti25Zr25Ni25Cu25 HEA filler.

Summary: This study optimized the deposition window of cold spray additive manufacturing (CSAM) for high-entropy alloy (HEA), focusing on the processing parameters' impact on deposition efficiency and porosity. The optimal parameters were determined as using helium as the driving gas, with a gas inlet temperature of 700 degrees C and a spray distance of 25 mm. These conditions resulted in the thickest deposit with the lowest porosity. The choice of driving gas is crucial, with helium being necessary to achieve high-quality HEA deposits. Gas inlet temperature and spray distance have minimal effects. Furthermore, higher gas temperature and moderate spraying distance were selected to enhance particle deformation and reduce shock wave effects at the plate front.

Summary: Al-Zn-Mg-Cu alloy joints were fabricated using 4 passes friction stir welding. The influence of different passes on the grain size, sub-grain structure, and kernel average misorientation of the stir zone (SZ) was investigated. The tensile properties and strain hardening behavior of the joints were evaluated. The results showed that the welding passes had minimal effect on the grain size of the SZ. The 3 passes joint exhibited the lowest sub-grain structure proportion in the SZ, leading to the best tensile properties and highest strain hardening rate in stage III.

Summary: Synergistic double-sided friction stir welding (DS-FSW) is proposed as a solution to the problems of large deformation and time consumption in traditional DS-FSW. The microstructure, mechanical properties, and fracture paths of novel and conventional joints are studied under different welding parameters. Results show the improved defects in novel joints, although the grain size in the stir zone is larger. The new joint also exhibits a more uniform distribution of microhardness compared to the conventional joint. At specific rotational and transverse speeds, the novel joint has less distortion and higher tensile force than the conventional joint.

Summary: This study investigates the use of negative thermal expansion (NTE) materials to alleviate high residual stress in brazed joints by regulating the coefficient of thermal expansion (CTE) of the metal composite filler. A new method of preparing a high-content Sc2W3O12 dispersed interlayer is proposed, increasing the optimal addition amount of Sc2W3O12 materials. The study demonstrates the potential of the proposed method for preparing brazed interlayer with high-content reinforcements and highlights practical applications in other metal composites.
