摘要：
The microstructure, phase composition, and oxidation resistance of as-cast high-entropy alloys (HEAs) Al0.25CoCrFeNi and Al0.25CoCrFeNiCuAgx (x = 0, 0.1, 0.2) have been studied. Oxidation was carried out at 700 degrees C for 50 h in air. During the experiment, curves for the dependence of the specific weight gain on the exposure time were plotted. It has been shown that the introduction of copper has a slight effect on the resistance of the base Al0.25CoCrFeNi HEA to oxidation, while additional (to copper) alloying with silver worsens the resistance of the samples to high-temperature gas corrosion.
