Improvement on Mechanical Properties of a bcc Matrix Al_8(FeCuCrMn)_92 High-Entropy Alloy by Phase Modulation of Interstitial Carbon Element

We present a method to increase the stability of a body-centered cubic matrix HEA without losing ductility. Since carbon increases the volume fraction of a face-centered cubic phase, carbon addition can increase strength and maintain good ductility in some steels while also increasing ductility. Carbon addition modulated constituent phases by increasing the volume fraction of fcc phase and carbides, according to our findings. However, the ductility dropped, especially when the carbon content was higher than 3 percent, which was attributed to uneven distribution of Cu-rich fcc phase and carbides precipitated in the bc phase zone. For this bc matrix HEA, it was shown that a proper carbon content addition with annealing could increase yield strength without loss of ductility. Thus, interstitial carbon addition is a useful way to improve the mechanical properties of the mechanical systems by phase modulation and other increasing effects. Carbon additions can improve the fraction of fcc phase and yield strength by phase modulation.
