Investigations on the Effect of Heat Treatment on Wear Behavior and Structure of Inconel 713 Alloy

In this study, tribological wear and Brinell hardness number characteristics of Inconel 713 alloy in its as-received state, following heat treatment was explored. The investigation focused on the effects of heat treatment at temperatures of −140 °C and −196 °C for durations of 24, 36, and 48 h using DCT Process. At room temperature, Inconel 713 alloy maintains a stable γ phase with a face-centered cubic (FCC) structure, which imparts excellent mechanical properties along with corrosion and oxidation resistance. However, despite its commendable mechanical traits, the alloy demonstrates insufficient wear resistance in cutting tool applications, prompting a quest for enhanced wear properties. Thus, this study endeavors to improve wear resistance by subjecting the specimen to a heat treatment environment, facilitating the transformation from austenite to martensite without embrittlement. Through comprehensive analysis, including examination of microstructure, wear behavior, and hardness, we aim to elucidate the alloy’s performance under these conditions.
