Alloy 617 is a solid solution strengthened alloy with nominal Ni-Cr-Co-Mo composition specifically designed for high-temperature applications51. Alloy 617 has been employed in nuclear components, intermediate heat exchangers, combustion liners for turbine engines, and pressure vessels, among others, ...
Inconel 617 has been a superalloy developed for use in the form of superheater and reheater tubing seen in the power plants operating in A-USC environments. There have been researches aiming at improving its creep resistance, and versions with optimum chemical composition have been developed. ...
Specifically, the composition, type, and crystallography of precipitates were determined and their evolution was related to process variables. Joints were characterized using optical and electron microscopy as well as microhardness testing. The results were analyzed in the framework of the diffusion, ...

In the present study, a heat treatment of the INCO-617 alloy previously used over 30,000 h is considered. Three heat treatment conditions are taken into account. The microstructures and elemental composition of the alloy before and after the heat treatment are investigated. It is found that ...
Fire-side corrosion behavior of Alloy 617 Bat 700℃ was evaluated in stimulated coal-ash and flue gas environment firing Liuzhicoal with high S content,on a self-built lfue gas corrosion test device.The morphology,composition and phase constitution of the Alloy 617 Bwere characterized through sev...
Building on the work and using the same coating process performed by Smith et al.33, a model-driven alloy design approach was employed to optimize the NiCoCr alloy system for high-temperature applications using AM for complex components. This effort resulted in a new composition that was built...
The previous works as reviewed above, indicated that the oxidation behavior of IN617 alloy was complicated, which depended on the interplay between temperatures, alloy composition and oxidizing environment. Recently, the addition of Ta was found to be beneficial to improving the high temperature ...
