Novel high-entropy and medium-entropy stainless steels with enhanced mechanical and anti-corrosion properties
Journal article, 2018

Novel high-entropy and medium-entropy stainless steels (MESS), containing a high amount of alloying elements, were designed and prepared by arc melting. These high-entropy and MESS possess a simple phase constitution, mainly solid solution phases, and noticeably exhibit excellent anti-corrosion properties in sulphuric acid. In particular, an austenitic Fe 65 Cr 13 Co 4.75 Mn 4.75 Mo 4.75 Ni 4.75 Cu 3 (at.-%) alloy has a higher hardness of 182 HV and better corrosion resistance than those of the 00Cr19Ni14Mn2 austenitic stainless steel prepared under the same condition; a ferritic precipitation hardening Fe 65 Cr 13 Al 3.167 Co 3.167 Mn 3.167 Mo 3.167 Ni 3.167 Ti 3.167 Cu 3 (at.-%) alloy was also developed, with a higher hardness of 584 HV and even better corrosion resistance.
