Abstract Scope |
New structural alloys are needed to enable more efficient power generation and conversion, including higher temperature tolerance in gas turbine generators and in nuclear fusion plasma containment. This presentation will review a recently validated general predictive model – with no fitting parameters – for the peak strength of metals, including high-entropy alloys, and explore ongoing work linking interstitial charge density, chemical ordering, and ductility in refractory BCC concentrated alloys. We will also present examples of how these computationally inexpensive methods are being used, coupled with high-throughput synthesis and experimental testing methods, to validate model predictions and support alloy design. |
