“…For instance, the addition of niobium diboride (NbB 2 ) nanoparticles strengthens a pure aluminum matrix used in wire fabrication [6,[13][14][15][16], showing improvements in strength, oxidation resistance, operating temperature, stiffness, wear resistance, and increasing the electrical conductivity [2,6,15,17]. A high strength-to-weight ratio makes these nanocomposite materials apt for structural applications [9,17,18]. Other materials that increase weld strength are titanium diborides, carbon nanotubes, and graphene nanosheets [2,17,19].…”

New and innovative technologies have expanded the quality and applications of aluminum welding in the maritime, aerospace, and automotive industries. One such technology is the addition of nanoparticles to aluminum matrices, resulting in improved strength, operating temperature, and stiffness. Furthermore, researchers continue to assess pertinent factors that improve the microstructure and mechanical characteristics of aluminum welding by enabling the optimization of the manufacturing process. Hence, this research explores alternatives, namely cost-effective aluminum welding fillers reinforced with niobium diboride nanoparticles. The goal has been to improve weld quality by employing multi-objective optimization, attained through a central composite design with a response surface model. The model considered three factors: the amount (weight percent) of nanoparticles, melt stirring speed, and melt stirring time. Filler hardness and porosity percentage served as response variables. The optimal parameters for manufacturing this novel filler for the processing conditions studied are 2% nanoparticles present in a melt stirred at 750 rpm for 35.2 s. The resulting filler possessed a 687.4 MPA Brinell hardness and low porosity, i.e., 3.9%. Overall, the results prove that the proposed experimental design successfully identified the optimal processing factors for manufacturing novel nanoparticle-reinforced fillers with improved mechanical properties for potential innovative applications across diverse industries.

In present experimental work, 310 SS alloy has been welded by the TIG welding using design of experiment and grey relation optimization techniques. The input parameters, i.e., welding current, welding gas flow rate, and welding voltage, have been selected to perform the TIG welding. The same filler material was used during the welding process to investigate the mechanical and microstructure properties. The design of experiment and grey relation optimization techniques were used to optimize the effect on hardness and tensile strength of the welded joints. The experiments were performed as per the L9 orthogonal array obtained by the design of experiment methodology. The 65 A, 12 V, and 7.5 gas flow rate optimum setting of input parameters provides the better results for the effective hardness and tensile strength. The most significant parameters, i.e., welding current with 84.93% and welding voltage with 65.09%, were obtained for hardness and tensile strength, respectively.

“…However, ceramic reinforcement with SiC particles leads to poor wettability on metals. In order to improve the quality of bonded joints, many researchers have done a lot of work on fusion welding [6], solid-state bonding [7][8][9], transient liquid phase bonding [7,10], laser welding [11], and brazing [12,13]. However, previous investigations show that a brittle Al 4 C 3 intermetallic compound (IMC) is formed during fusion welding.…”

Rapidly solidified Al–8.5Si–25Cu– xY (wt-%, x = 0, 0.05, 0.1, 0.2, 0.3, 0.4, and 0.5) foils were used as filler metal to braze Al matrix composites with high SiC particle content (SiCp/Al-MMCs), and the filler presented fine microstructure and good wettability on the composites. The joint shear strength first increased, then decreased and a sound joint with a maximum shear strength of 135.32 MPa was achieved using Al–8.5Si–25Cu–0.3Y as the filler metal. After Y exceeded 0.3%, a needle-like intermetallic compound, Al3Y, was found in the brazing seam, resulting in a dramatic decline in the shear strength of the brazed joints. In this research, the Al–8.5Si–25Cu–0.3Y filler metal foil was found to be suitable for the brazing of SiCp/Al-MMCs with high SiC particle content.
