Abstract Scope |
Data-driven, machine learning based modeling approaches have been shown to reduce the experimental burden in discovering novel materials in large compositional spaces. Cost savings arise by reducing the parameter space to search and uncovering subtle complex hidden correlations among materials properties and chemical features; however, models must be experimentally validated to be effective. NiTi-based shape memory alloys (SMA) are uniquely complex in their thermally activated solid state transformation that results in shape memory effect. Ternary, quaternary, and quinary additions have been shown to effect both mechanical and transformation properties of SMAs. Chemical variations as small as 0.1 at. % can render an optimized material unusable in application. This presentation reviews the work to create materials that fully transform between 200° and 300°C while minimizing hysteresis.
