| Abstract Scope |
Current ferritic superalloys for high-temperature applications currently still possess relatively low strength, limiting their lifetime and range of application. In this study, we utilized Calculation of PHAse Diagram (CALPHAD) to do high-throughput discovery to design high-entropy alloys that are lightweight, low-cost, and strong for high-temperature applications. High-throughput screening was employed to sort the alloys with predicted criteria satisfying the design, which yielded precipitation-strengthened lightweight high-entropy alloys. The strengthening mechanisms of failed and successful cases of the alloy composition discovered are studied experimentally and theoretically to improve the thermodynamic-database accuracy. This study accelerated the process of discovering high-entropy alloys with advanced properties by integrating high-throughput screening, multiscale modeling, and experimental validation. |
