abstract = "Brazing-repairRepairof nickel-based superalloyNickel-based superalloy precision casting has attracted a wide concern as the issues related to hot crackingCracking, dimensional distortion and loss of strengthening phase have not been solved for a long term. In this study, we proposed to use atomic clusterAtomic cluster powder filler which was manufactured through mechanical ball-mixing of Ni atomic clusterAtomic cluster nanoparticles with Inconel 718 powders to achieve a well-bonded joint. Spark plasma diffusion bondingDiffusion bonding was conducted to evaluate the atomic clusterAtomic cluster powder fillers and Inconel 718 powder fillers counterpart. The microstructureMicrostructure and mechanical propertiesMechanical properties of bonding joints were investigated to explore the effects of atomic clusterAtomic cluster nanoparticles on bonding of superalloysSuperalloys. It was found that the Ni atomic clusterAtomic cluster nanoparticles were uniformly distributed into Inconel 718 powders. The joint of atomic clusterAtomic cluster powder fillers exhibited a higher densificationDensification increased by 42% compared with Inconel 718 powder fillers. The tensile mechanical propertiesMechanical properties of bonded sample will be dependent on the bonding interface quality rather than microstructureMicrostructure of joint region. The atomic clusterAtomic cluster powder fillers resulted in a comparable yield strength of bonded sample with 200 K lower bonding temperature compared with Inconel 718 powder fillers.",
