Analysis of structure and strength properties of heat‑resistant iron‑chromium‑nickel (Inconel 718) alloy obtained using secondary metal powder composition in direct laser deposition
This work presents investigations on the structure, chemical analysis, and strength properties of deposited metal using two types of metal powder compositions, namely the primary powder and the residuals (secondary) of the heat‑resistant ironchromium‑nickel alloy Inconel 718.Based on the obtained results, the causes of the formation of a fine‑cellular‑dendritic directional structure with needle and dendritic morphology were determined, as well as the decrease in heat resistance of the deposited material from the secondary powder of the heat‑resistant iron‑chromium‑nickel alloy Inconel 718 at elevated temperatures.
