A novel alloy design for non-equiatomic high-entropy alloy (Cr-Fe-Ni-Ti-Nb): predicting entropy mix and enthalpy mix

Alloy having at least five primary elements, each with a concentration range from 5 to 35 at.%, were referred to as HEAs. Due to their exceptional multi-component characteristics, high-entropy alloys (HEAs) have captured the interest of academics and industrial high temperature applications. Alloy Design calculations of new HEAs provides better understanding of the physical mechanism and eradicate the trial and error experimental process. Therefore, the goal of the current research is to create a novel non -equiatomic high entropy alloy (Cr-Fe-Ni-Ti-Nb) with varying their composition were investigated in an effort to predict the Entropy mix, Enthalpy mix and Gibbs Free Energy. The relationship between the Entropy mix and Enthalpy mix is vitally important for non-equiatomic high entropy alloy design to distinguish the single phase and inter-metallic phase formation in Cr-Fe-Ni-Ti-Nb HEA for various concentration of each elements. The capacity to evaluate phase structure in non-equiatomic systems Cr-Fe-Ni-Ti-Nb HEA would benefit the alloy design to obtain the desired properties for industrial applications.
