Microstructure and Electrochemical Performances of AlxFeCoNiCr(B) High Entropy Alloys
High entropy alloys are new alloys composed of over five principal elements with each having an atomic percentage in the range of 5%~35%,which break through the concept of traditional alloys design.In this paper,AlxFeCoNiCr(B) high entropy alloys were prepared in an vacuum arc induction melting furnace.The microstructure presents simple solid solution structure,and the fraction of FCC crystal structure decreased with increasing of Al content.Chromium tends to segregate at the inter-dendrite grain boundary.Electrochemical investigations indicated that AlxFeCoNiCr(B) high entropy alloys were more corrosion resistance than 316L stainless steel.
