The Effect of Heat Treatment and Tungsten Content on the Structure, Phase Composition, and Corrosion Resistance of High-Entropy Alloys of the Fe–Cr–Ni–Mo–W System
Inorganic Materials: Applied Research(2024)
摘要
Abstract—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.
