| Abstract Scope |
The development of next-generation Ni-based superalloy materials that can withstand higher temperatures will require an intricate understanding of the effect of location-specific control of heat treatment schedules on microstructure development and subsequent performance in relevant environments. As such, the effect of three different cooling rates on microstructure development and subsequent mechanical behavior at elevated temperatures was studied for three different Ni-based superalloys, namely, Udimet 720Li, Haynes 230, and Inconel 718. The creep resistance was evaluated at temperatures ranging from 800° to 1100° C. High-resolution scanning electron microscope images of the gauge section were taken pre- and post-test and co-registered with in-situ digital image correlation images. Understanding the effects that cooling rates have on the oxidation, strength, ductility, and creep resistance of the material can help provide critical property data that can enable a more robust design and life management process for high temperature material components. |
