Abstract
High-entropy alloy with multi-principal elements is a novel design concept for the field of alloy, which breaks through the traditional alloy development frame based on “one or two major alloy elements”. High entropy alloy composed of different metallic elements (generally ≥ 5) can present different novel properties by changing mole ratios or elements. In this work, the valence electron structure of high entropy alloys with compositions near Nb25Mo25Ta25W25 and V20Nb20Mo20Ta20W20 was studied using the Empirical Electron Theory of Solid and Molecules (EET). The predicted results agree well with the experimental data. Results shows that EET can be used to forecast the HEAs’ properties and design the constituent of HEAs.
