摘要：

The effect of heat treatment (diffusion annealing, quenching, low-temperature and high-temperature tempering) on the structure, phase composition, and corrosion resistance of high-entropy 35Fe-30Cr-20Ni-10Mo-5W and 30Fe-30Cr-20Ni-10Mo-10W alloys has been studied. High-entropy alloys of the Fe-Cr-Ni-Mo-W system with different concentrations of tungsten are obtained by sintering mechanically alloyed powders in a vacuum furnace. It is revealed that the total and pitting resistance of the obtained high-entropy alloys to aqueous solutions of NaCl is higher than that of industrially produced austenitic corrosion-resistant steel 316L used in the oil and gas industry.
