Improvement on Mechanical Properties of a bcc Matrix Al8(FeCuCrMn)92 High-Entropy Alloy by Phase Modulation of Interstitial Carbon Element

High-entropy alloys (HEAs) are novel multi-element alloys based on five or more constituent elements in a range of 5–35 at%. Here we present a method to improve strength of a body-centered cubic (bcc) matrix HEA without loss of ductility. The improvement was achieved by phase modulation combined other strengthening effect of interstitial carbon addition. Carbon addition can enhance strength and retain good ductility in some steels because carbon...
