| Abstract Scope |
The rise of digital alloy discovery has significantly accelerated the development of novel alloy compositions tailored for specific applications. However, a key challenge remains how to efficiently screen and rank these computationally suggested alloys based on targeted mechanical properties without resorting to time and resource intensive conventional testing methods. Fracture toughness, a critical property for structural applications, typically requires large quantities of material and extended testing durations using standard bulk specimens. In contrast, nanoindentation provides a rapid, small-scale technique capable of extracting key mechanical properties including hardness and elastic modulus with minimal material requirements. This presentation explores correlations between nanoindentation-derived properties and fracture toughness measured through conventional methods. By establishing empirical relationships between these datasets, we aim to enable a predictive framework that allows efficient pre-screening and ranking of digital alloy candidates, thereby bridging the gap between computational alloy design and experimental validation. |
