In-situ composite formation of vanadium carbide in CrFeCoNiCu high-entropy alloy cladded on AISI304 stainless steel

In the present study, CrFeCoNiCu(VC)x (x = 0, 1, and 2) high-entropy alloy (HEA) composites were cladded on AISI304 stainless steel using tungsten-inert gas (TIG) cladding.For this purpose, elemental powders of Cr, Co, Fe, Ni, and Cu together with V and C were mechanically mixed, and then by adding the proper amount of polyvinyl alcohol as a AC Cha
