| Abstract Scope |
Ordered high-entropy body-centered-cubic (BCC) phases with the B2 structures, particularly those formed with refractory elements and aluminum (Al-RHEAs), are of interest due to their high strength, corrosion resistance, and oxidation resistance. The incorporation of Al lowers the density and promotes the long-range atomic ordering, which in turn stabilizes the B2 formation, and strengthens the material but usually deteriorates ductility. B2 Al-RHEAs are screened using machine learning (ML) models to predict B2 formation and toughness. High prediction accuracy is achieved. Several Al-RHEAs have shown large compression plasticity and high strength and exhibit some tensile ductility. |
