Abstract
A high-entropy alloy includes a single-phase, face centered cubic structure composition containing between 43.0 and 49.9 at% nickel, between 16.0 and 26.0 at% chromium, between 6.5 and 16.5 at% iron, between 1.5 and 4.5 at% molybdenum, between 2.0 and 7.5 at% aluminum and between 6.5 and 11.0 at% cobalt. Such compositions are good replacements for more expensive nickel-based alloys and have good strength and corrosion resistance properties.
