Zusammenfassung: | To provide a metallurgical green compact having high entropy of mixing ΔSmix and excellent in corrosion resistance and in hot workability as well.SOLUTION: A green compact is obtainable from a powder. The powder is of a multi-component alloy. The multi-component alloy contains Co: 5 atom% or more and 35 atom% or less, Cr: 5 atom% or more and 35 atom% or less, Fe: 5 atom% or more and 35 atom% or less, Ni: 5 atom% or more and 35 atom% or less, Cu: 0.10 atom% or more and 7.00 atom% or less, and inevitable impurities. The multi-component alloy has an entropy of mixing ΔSmix of 1.30R or greater.SELECTED DRAWING: None
