| Abstract Scope |
Additive manufacturing (AM) is quickly penetrating the manufacturing community as a method of processing parts with complex part geometries and full assembly integration, especially of importance to applications in high temperature or harsh service environments. With the advent of the alternate kinetics inherent to the AM process, new alloy families amenable to rapid solidification, such as high entropy alloys (HEAs), become of great interest. Development of new AM-tailored alloys needs to be accelerated using computational models and validated via high-throughput experimental processes, to drastically shorten the time-to-market of AM. This work will describe the electronic structure modeling of HEA compositions, rapid, science-based alloy selection and experimental validation of the most promising chemistries, including the subsequent AM processing of the HEAs with the most desirable potential combination of properties. This work was funded by the U.S. Department of Energy’s - Energy Efficiency and Renewable Energy - Advanced Manufacturing Office. |
