Abstract:CoCrFeNiMnTi x ( x = 0.5, 1.0, 1.5, 2.0 in atomic ratio) high entropy alloy (HEA) coatings were prepared on 304 stainless steel by laser cladding. Experimental results showed that the CoCrFeNiMnTi x HEAs constituent phase evolved from a single FCC phase for the HEA to FCC + BCC + Intermetallic + Laves phases with the addition of Ti element. The CoCrFeNiMnTi x coatings exhibited an increasing microhardness from 412.42 HV to 573.97 HV. Accompanying the increase in microhardness, the wear resistance was proportio… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
