Abstract

The microstructure and phase composition of cast AlCoCr0.5NiY0.1 multi-principal element alloy (MPEA) have been determined. High-temperature oxidation of the alloy under study was carried out at 1100°C for 100 h in an atmospheric atmosphere. The high resistance of this MPEA to high-temperature gas corrosion is shown, the parabolic oxidation rate constant was kp = 9.48 × 10-13 g2 cm-4 s-1. It has been established that the introduction of yttrium is an effective way to increase the heat resistance of multi-principal element alloys.
