The well-known FeCoCrNi HEA (High Entropy Alloys) has been produced by induction furnace using inexpensive industrial grade raw materials and cast into cylindrical shape molds. Another set of FeCoCrNi HEA has been produced from high purity raw materials to compare the effect of purity of raw materials. The structural characterization (SEM, XRD) and mechanical tests (Tensile and Hardness) were applied to both alloys produced with different precursors. XRD and SEM analyses show that in addition to the fcc, Cr7C3 intermetallic phase present in the low grade FeCoCrNi HEA. This additional phase increases the mechanical properties of the alloy in a manner similar to precipitation hardening. The failure behavior of selected of FeCoCrNi HEA has been investigated for high and low purity precursors. The results correlating the microstructure with mechanical and purity of the raw materials will be discussed in details.
