“…The composition of IN718 superalloys comprises elements such as Ni, Cr, Nb, Mo, Fe, Co, etc. The addition of the Co element of nickel-based superalloys can increase the content of γ phase and reduce the stacking fault energy [8]. The interdendritic phases evolve from lath and eutectic Laves phases to blocky P phases with a decrease in Cr/Mo ratio [9].…”

A novel IN718 superalloy has been designed based on the commercial IN718 alloy to improve its service performance in the aerospace field. Firstly, first principle calculations were performed to determine the total energy, formation enthalpy, and binding energy of the γ-Ni phase, Laves-Fe2Nb phase, and γ-Ni/Fe2Nb interface model doped with Co, Cr, Mo, V, and Zr atoms in IN718 superalloy. The calculation results reveal the influence of various atoms doping on the typical phases of the IN718 superalloy. Secondly, 8488 group’s suitable alloy composition data were selected from 831600 group’s datasets by D-electron theory and Python programs. Subsequently, the optimal alloy components were determined by thermodynamic calculations using the control variable. Finally, molecular dynamics tensile simulations and mechanical properties tests were conducted to validate the mechanical properties of the optimized superalloy. This entire calculation process serves as a reference for designing other alloy compositions.

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.
