文摘

CoCrFeNiMn high entropy alloy doped with 1 at.% C was produced by vacuum arc melting. After homogenization annealing at 1000 °C the alloy has single fcc phase structure. The alloy was cold rolled to 80% thickness strain and annealed at 600–1100 °C. After annealing at 800 °C the alloy combines high strength with good ductility. High strength of the annealed alloy mainly is due to strong Hell-Petch strengthening.
