Characterization of AlCoCrFeNiVTi High Entropy Alloy Produced with Different Alloying Sources

High-entropy alloys offer a simpler alternative to the precise balance of binary alloy designs in terms of chemical composition. Such alloys consist of at least five basic metallic elements with solute elements that have relatively similar atomic sizes, resulting in a roughly equimolar ratio. Alloys produced using this method exhibit extraordinary physical properties, attracting the attention of researchers. However, for them to be viable for industrial production, their economic value must also be reasonable. In this study, high-purity and commercial alloying elements were used to produce samples by arc melting. Structural analysis was conducted on the resulting samples, and the differences in their structural characteristics were examined through heat treatment. The high-purity high-entropy alloy samples showed a structure similar to that of the commercially pure sample before heat treatment. However, after heat treatment, it was found that different structures had formed in the commercial sample, likely due to the presence of small amounts of impurities in the content of the commercially pure alloy.
