A high entropy alloy, Al8Co17Cr17Cu8Fe17Ni33, has been developed from an equiatomic AlCoCrCuFeNi alloy. Due to its promising properties, such as high corrosion and oxidation resistance and high thermal stability, it is a candidate for various applications at elevated temperature as, e.g., furnace parts, tools and moulds. The exploration of new metallic systems for high-temperature applications is an important challenge in today’s materials science.
However, an increase in the strength of this alloy is desirable and requires further optimization. In order to improve these mechanical properties, knowledge of the microstructure is necessary. Therefore, Al8Co17Cr17Cu8Fe17Ni33 high entropy alloy has been studied by means of energy-dispersive X-ray spectroscopy (EDS) and electron backscatter diffraction (EBSD).
