“…Eventually, because Inconel 625 can withstand corrosion from seawater, it is widely used in the nuclear and marine industries [3]. Numerous traditional manufacturing techniques, including melting and solidification processes, spray forming, cladding, bimetallic extrusion of components, and powder metallurgy have been used to create Inconel 625 components [4]. Unfortunately, a lot of products made using Inconel 625 have intricate shapes, making conventional fabrication exceedingly costly.…”

This article provides a comprehensive review of the research progress in the tribology of nickel‐based superalloys (NBS). First, the microstructure, friction, and wear characteristics of NBS are summarized. Second, the tribological features of NBS and the effects of environmental factors on tribological behavior and wear mechanism are elucidated. Third, the microstructure and the corresponding formation mechanism of the NBS tribolayers and the oxidation behavior during friction are analyzed. Fourth, the effect of tribolayer formation on the friction state and wear mechanism is discussed. Moreover, the application of existing finite element simulation technology in NBS friction and wear is reviewed. Finally, the strain‐induced gradient structure (i.e., strengthening layer) is introduced, and the benefits of the gradient structure in the frictional process are analyzed in comparison with the coarse grain. According to these existing reports, future research should focus on elucidating the quantitative relationship between friction state and wear mechanism, investigating the design of wear‐resistant NBS, and expanding its potential applications. These advancements provide a pathway for thoroughly elucidating NBS tribology and promoting the application of strengthening technologies.

Herein, we developed a process window for Ni625 alloy fabricated using a Nikon Lasermeister laser powder direct energy deposition unit. The process map illustrates the relationship between the laser power, scan speed, and effective energy density, established by examining the correlation between the microstructure and mechanical properties. All samples exhibited a bimodal microstructure comprising equiaxed and columnar dendrite grains, and the dendrite arm spacing decreased with increasing scan speed. The tensile behavior of each sample demonstrated minimal variation, and the values were comparable to those reported previously. The ultimate tensile and yield strengths ranged from 1008 ± 2 to 941 ± 9 and 682 ± 11 to 640 ± 7 MPa, respectively. This study highlights the remarkable manufacturability of Ni625 alloy for additive manufacturing across diverse parameter sets, demonstrating that a single ideal process set does not exist for each material and machine. Instead, multiple “recipes” may be employed to achieve similar outcomes.This article is protected by copyright. All rights reserved.
