Abstract Additive manufacturing is expected to be the manufacturing method for components made with high-entropy alloys (HEAs). In this study, the mechanical and electrochemical behaviors were investigated for equi-molar HEA (AlCoCrFeNi) obtained with selective electron beam melting (SEBM). The mechanical properties of SEBM products were improved compared with those of a cast specimen. Electrochemical measurements in artificial seawater revealed the corrosion behaviors of HEA (AlCoCrFeNi). The pitting potential of SEBM specimens (0.112 V vs. Ag/AgCl) was lower than that of a cast specimen (0.178 V vs. Ag/AgCl). The mechanical and electrochemical properties of SEBM products were influenced by the phase morphologies formed during the SEBM process.
