Abstract
A metallic alloy, more particularly, a high-entropy alloy with a composite structure exhibits high strength and good ductility, and is used as a component material in electromagnetic, chemical, shipbuilding, machinery, and other applications, and in extreme environments, and the like.
Claims4
A high-entropy alloy having a composite structure, comprising:
- by weight %, iron (Fe) greater than 5% to 35% or less, manganese (Mn) greater than 5% to 35% or less, nickel (Ni) greater than 5% to 35% or less, and cobalt (Co) greater than 5% to 35% or less,
- and comprising, by weight %, at least one of copper (Cu) greater than 3% to 40% or less and silver (Ag) greater than 3% to 40% or less,
- wherein a ductile second phase is distributed in a matrix of the high-entropy alloy and the ductile second phase has a filament structure formed by deformation processing.
