Abstract

Equiatomic CrMnFeCoNi high-entropy alloy was joined in solid-state by electrically assisted pressure joining (EAPJ). Cracks and compositional segregation were not found in joining zones (JZ). As the applied electric current increased, the microstructure of JZ changed from a deformed and partially recrystallized microstructure to a fully recrystallized one with grain growth. JZ showed sound mechanical properties through the Vickers hardness and uniaxial tension results. EAPJ of high-entropy alloy can overcome the disadvantage of fusion welding.
