Abstract
Abstract High entropy alloys are one of the most developing classes of materials of the 21st century. Their properties can significantly vary depending on their chemical composition and processing method. Thus, the microstructure and mechanical properties of CoCrFeMnNi high entropy alloy prepared by conventional casting, melt-spinning and mechanical alloying were investigated in this study. The observed structure and grain size were typical for this type of alloy and production methods. It was found that the hardness of the sample prepared by mechanical alloying with subsequent spark plasma sintering is higher compared to cast and melt-spun samples due to the finer microstructure and higher deformation energy stored.
