A FRESH PERSPECTIVE ON MEDIUM ENTROPY ALLOYS APPLICATIONS AS COATING AND COATING SUBSTRATE

In order to evolve as a society we need increasingly efficient technologies and implicitly materials with great performance that promote safety and sustainability. The discovery of high entropy alloys was received with much enthusiasm due to the possibility of designing new materials with improved properties, that could be used in applications that require extreme conditions or a very specific combination of properties. As the research in this area is continuously increasing and the results are very promising, this review focuses on the most recent investigations on medium entropy alloys (MEAs) applications, highlighting their properties, but taking into consideration other factors, such as economic and environmental factors. Additionally, considering the high cost associated with MEAs fabrication, MEA coatings are also explored, as they are nowadays regarded as a more convenient procedure to obtain the required properties for various substrate materials.
