This is a SEM (Scanning Electron Microscope) image of novel AlCrFeNiNb0.3 high entropy alloy showing complex microstructure. High entropy alloys (HEA) present novel metallurgical approach. Instead of commonly used alloying of one major constituent, in HEAs – 4-6 principal elements are used with a concentration of 5¸35at.% yielding a solid solution. The AlCrFeNiNb0.3 HEA solidifies dendritically and The image shows both the dendrite and the interdendrite regions.
