Effect of heat treatment on the mechanical and corrosion properties of the CoCrNiFeAl HEAs
Abstract
dc:description.abstractHigh entropy alloys (HEAs) are a relatively new class of metallic materials that have shown great potential for use in extreme environments, such as high temperatures and corrosive conditions. Among the different types of HEAs, CoCrNiFeAl HEAs are potential materials for a wide range of applications, including aerospace, biomedical, and energy storage. This work focused on the effects of heat treatment temperatures from 800 °C to 1100 °C on the microstructure and mechanical properties of these alloys, as well as their electrochemical corrosion behavior. A thermodynamic model was implemented to predict the performance of the material. The results of this study provide a good insight into the potential of CoCrNiFeAl HEAs 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.
