“…Furthermore, superalloys are superior to conventional alloys because of their high-temperature endurance performance, high corrosion resistance, high strength, fatigue, and creep resistance [2][3][4][5][6]. However, the fabrication of superalloys is expensive [7][8][9][10]. Thus, researchers are investigating solutions such as joining to minimize maintenance (replacing a part), and welding techniques have become the main joining processes because of several advantages such as affordability, low downtime, user-friendliness, and availability.…”

This study investigates solid-state diffusion bonding between two INCONEl 617 alloy samples using field-assisted sintering technology (FAST). The study focuses on analyzing the faying surface validating the theoretical alloy design modeling done by the CALculation of PHAse Diagrams (CALPHAD) approach followed by experimental validation. Varying kinetics’ limitations enabled phase stability and phase control governed by the CALPHAD approach alloy design. The alloy design contains a pseudo-binary phase diagram assisted with thermal mapping of a property phase diagram to obtain the optimum temperature of solid-state diffusion bonding while understanding phase fields and their evolution through Mo-increasing content and temperature increase. The FAST parameters recommended by CALPHAD were 800 °C under 10 MPa pressure with a holding time of 30 minutes. The investigation observations were promising where the faying surface contains γ only, while the further region on the alloy contains γ and γ`. It is worth mentioning that FAST advantage resulted in fine faying surface thickness of around 10 µm and a controlled heat affected zone (HAZ) leading to extreme reduction in recrystallization zone yielding an average grain size of 60-100 µm before and after diffusion bonding. Furthermore, two modes of metal carbide (MC) have been found, MC formed under the faying surface and micro-MC pools formed around the faying surface.

This study employs molecular dynamics simulations to investigate the nanoscale tribological behavior of a single transverse grain boundary in a nickel-based polycrystalline alloy. A series of simulations were conducted using a repetitive rotational friction method to explore the mechanisms by which different grain boundary positions influence variations in wear depth, friction force, friction coefficient, dislocation, stress, and internal damage during repeated friction processes. The results reveal that the grain boundary structure enhances the strength of the nanoscale nickel-based polycrystalline alloy. When the friction surface is far from the transverse grain boundary, the grain boundary's obstructive effect is weaker, leading to larger ranges of atomic displacement and migration of internal defects. This results in smaller fluctuations in friction force and coefficient, along with the formation of numerous densely packed downward defect bundles. At the grain boundary, two grains undergo relative slip along the grain boundary interface, while atoms below the grain boundary remain largely unaffected. When the grain boundary is closer to the friction surface, more wear debris atoms accumulate in front of and on the sides of the friction grinding ball, increasing the friction force during the process. If the friction grinding ball breaches the grain boundary layer, its supporting and strengthening effects are diminished, leading to a significantly greater wear depth compared to when the grain boundary remains intact.
