Abstract AITranslate

The effects of different content of interstitial carbon atoms on the microstructure and properties of Fe50Mn30Co10Cr10 as-cast high-entropy alloy were analyzed by means of XRD,OM,EBSD and SEM.The results show that phase composition of the as-cast alloy changes from FCC+HCP two phases to FCC single phase with the increase of carbon content.The CrxCy carbide precipitates in the grain boundary and within the grains of the matrix when the molar fraction of carbon atoms reaches 4%,which deteriorates the ductility of the alloy.When the molar fraction of carbon atoms is 2%,(Fe50Mn30Co10Cr10)98C2 high-entropy alloy has the best comprehensive mechanical properties due to the obvious TWIP effect.
