| Abstract Scope |
Automotive applications need low-cost, lightweight, high-temperature alloys to increase vehicle efficiency. The Al–Fe–Si system provides an opportunity to develop such a material, as it consists of three low-cost elements that are all abundant in nature. However, this alloy system is filled with complex, low solubility phases. Thus, a phase that shows promising thermomechanical properties yet exhibits a narrow compositional range of stability would be undesirable, limiting its use in potential applications. A computationally guided experimental approach was used to increase thermodynamic phase stability. This presentation will illustrate a materials design methodology to developing novel intermetallic alloys by parametrizing thermodynamic, kinetic, and microstructural features to optimize properties and performance. |
