| Abstract Scope |
FeMnAlC alloys have been studied for decades given their outstanding mechanical properties, reduced density, and potential applications in automotive and aerospace industries. However, several challenges remain in understanding their intricate relationships among processing, microstructure, and manufacturing. In this study, a series of Medium- and High-entropy FeMnAlC-based alloys have been developed with the aid of CALPHAD tools. A wide range of thermo-mechanical processing conditions have been explored to identify suitable microstructures and mechanical properties for automotive applications. These alloys exhibit dual-phase microstructures while also containing nano- and micro-sized Kappa-Carbides, TWIP and TRIP deformation mechanisms, high-strength and ductility, and reduced density compared to most conventional steels. Additionally, their manufacturing and processing in industrial-scale, as well as economic viability, will be evaluated. |
