| Abstract Scope |
Inconel 625, a nickel-based superalloy that is extensively utilized in high-temperature applications due to its exceptional mechanical properties and therefore, it is vital to ascertain the performance of the alloy under high-temperature environments. The current study involved fabrication of IN625 using additive friction stir deposition (AFSD), an innovative solid-state additive manufacturing technique driven by complex thermo-mechanical conditions. The oxidation behavior of the AFSD processed IN625 alloy was examined by subjecting the samples to various heating rates (10, 100, and 1000°C/min) under controlled oxygen environment in a thermal gravimetric analyzer (TGA). Cross-sectional electron microscopy using EBSD and TEM was carried out to understand the microstructure evolution of oxidized samples. Miniature tensile testing was employed to study the mechanical behavior of AFSD and wrought alloys up to 900°C. The talk will focus on the correlation between microstructure, high temperature oxidation behavior and mechanical properties in AFSD processed IN625 material system. |
