Abstract:
High entropy alloys (HEA) are a relatively new class of metallic materials composed of five or more elements, each typically present in an equal or nearly equal atomic fraction. This complex microstructure has shown great potential for use in extreme environments, such as high temperatures and corrosive conditions due to their exceptional mechanical and physical properties, such as high strength, hardness, and corrosion resistance. Among the different types of HEA, CoCrNiFeAl have shown promise as potential materials for a wide range of applications, including aerospace, biomedical, and energy storage. Although the microstructure characterization of these alloys was investigated widely previously but still the effect of different environments need to be studied. This study focused on the effects of different heat treatment temperatures from 800? to 1100? on the microstructure and mechanical properties of these alloys, as well as their electrochemical behavior. A thermodynamic model was implemented to predict the material performance. The results of this study provide a good insight into the potential of CoCrNiFeAl HEA to be employed in different applications, as the heat treatment improved the corrosion properties and decreased the corrosion rate compared to the as-cast alloys, while the surface hardness was affected negatively by increasing the heat treatment conditions.<\/p>\n","protected":false},"excerpt":{"rendered":"
