Design of a Seven-Component Eutectic High-Entropy Alloy

A eutectic high-entropy alloy with seven components (Fe, Ni, Cr, V, Co, Mn, and Nb) was designed via the melt route guided by CALPHAD predictions. Configurational entropy estimated for the two-phase microstructure qualifies it to be referred to as a high-entropy alloy. When the Nb content exceeded 9.7 at. pct, the microstructure changed from hypoeutectic with primary face-centered cubic phase to hypereutectic with primary Laves phase.


M.R. Rahul would like to acknowledge B. Nithin, Shah Naishalkumar Sanjay, and Sumanta Samal for useful discussions.
