Abstract Scope |
The design complexities with advancement in technology limit operational efficiency and conventional manufacturing ability of Nickel-based superalloy 718 (IN718). Additive manufacturing (AM) can overcome these drawbacks by producing near net shape components; however, a thorough understanding of mechanical behavior at elevated temperature and different loading conditions (i.e., tension and compression) is required before its actual use. In this work, process-induced history effects on the creep behavior in an additively manufactured IN718 alloy were investigated. In particular, three different heat treatment routes were chosen to tailor the microstructure by having the specific dissolution of precipitated phases. Compression and tensile creep experiments along with advanced characterization were performed to understand the role of microstructure. Results showed that the creep properties were dependent on the nature of phases present with a tension-compression asymmetry and are comparable to wrought behavior with a proper heat treatment condition. |
