Vacuum furnace cast FeCoNiCuMn high-entropy alloy was annealed at four conditions: the temperatures of 850°C and 1000°C for 2 and 12 hours. The effect of heat treatment on microstructure was investigated using optical and scanning electron microscopy. The corrosion resistance of the samples was also studied using linear polarization method. The results of Tofel extrapolation revealed that annealing at 850°C reduced the icorr, while the maximum studied temperature and time of heating made the corrosion resistance worse than the as-cast sample. All samples exhibited satisfactory corrosion resistance in a 3.5% NaCl solution
