Abstract:
High entropy alloys are a new class of advanced materials with considerable potential for achieving excellent properties not found in other materials, making them attractive for various applications. This study investigated the production of the CrMnFeCoNi alloy using the High Energy Milling (HEM) technique for 5, 10, and 20 hours. The powders were characterized by Scanning Electron Microscopy (SEM), Energy Dispersive Spectroscopy (EDS) and X-ray Diffraction (XRD). It was observed that increasing the milling time caused deformation, flattening, fracturing, and larger particle agglomeration, along with better distribution of the elements and the formation of a single phase. XRD analysis revealed FCC phase peaks and a reduction in crystallite size, with increased FWHM values and microstrain. The sample subject to the longest milling time exhibited improved homogenization and increased amorphization of secondary phases, attributed to the high energy applied during the process.
