Charpy impact toughness of Cu-Fe-Mn-based immiscible medium-entropy alloys

Impact toughness at ambient and cryogenic temperatures was investigated with systematic fracture analyses for CuFeMn and Al15(CuFeMn)85 (at%) immiscible medium-entropy alloys. These two types of alloys exhibited different impact toughness behavior at different temperatures, while exhibiting higher impact toughness values than those of dual-phase steels with a similar strength level.
