Effect of heat treatments on the microstructure and hardness of high-entropy alloy
 Jesenská, Mária Ľudmila ; Adam, Ondřej (oponent) ; Moravčíková de Almeida Gouvea, Larissa (vedoucí práce)
In this work, a non-equiatomic Al0.2Co1.5CrFeNi1.5Ti high-entropy alloy was produced through the vacuum induction melting process. The as-cast alloy was analyzed, then heat treated at 1000 °C for 5h, and subsequent heat treatment at 750 °C for an additional 5h took place, in order to investigate the effect of heat treatment temperature and time on the phase composition, microstructure, and mechanical properties of the alloy in all states. A pseudo binary phase diagram (CALPHAD) was performed to evaluate the possible phases present in the alloy. The alloy‘s microstructures were characterized and analyzed chemically by X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy dispersive spectroscopy (EDS). Microhardness and nanoindentation testing was performed to evaluate the hardness of the material.
