| Abstract Scope |
The discovery of new structural materials is slow, costly and limited, particularly for applications in extreme conditions that are challenging to mimic. To address this challenge with a focus on high temperature applications, we are developing a framework to discover new structural refractories with mission-specific properties to enable enhanced capabilities in applications such as hypersonic flight. Powder directed energy deposition is used to explore the combined effects of varied composition (Nb-Vi-Ti alloy space) and process parameters. Custom-designed mechanical test specimens are fabricated across a range of compositions and process parameters in a combinatorial fashion. These specimens are then autonomously characterized using a newly developed high throughput, robotic mechanical screening approach across ambient and elevated temperatures. The data are then fed into a Bayesian optimization framework, which recommends compositions and process parameters for future evaluation. This approach has potential to rapidly accelerate structural alloy development for high temperature applications. |
