“…However, they frequently lack hardness and ductility, which makes them di cult to form and shape. The alloy's practical applicability in chemical processing applications depends on improving its ductility and toughness while keeping other desired qualities [12]. AlCrFeNiMn HEA can be susceptible to localized corrosion phenomena such as pitting corrosion and crevice corrosion [13].…”

The development of novel corrosion-resistant components is essential since malfunction of materials like super alloys during industrial applications might cause financial loss. Arc-melting and casting were used to create AlCrFeCuNi high entropy alloys (HEAs), which were then doped with various atomic percentages of copper (Cu). Investigations were conducted into the effects of Cu on the evolution of microstructural features, corrosion behavior in various solutions, nano hardness, and thermal stability. The alloy samples had a dendritic microstructure with three different phase zones, as seen by scanning electron micrographs, and EDS validated the elements that were included into the alloys. The behavior of the HEAs' nano hardness and corrosion resistance significantly improved with the addition of Cu. In NaOH and Na2SO4 solutions, 3 at.% Cu samples demonstrated superior resistance to corrosion. With NaCl and H2SO4 solutions, 5 at.% Cu samples displayed greater corrosion resistance. The sample with 1 at.% Cu showed superior corrosion resistance in HCl solution.
