| description | To provide a powder molding made of an alloy high in mixing entropy ΔSmix, and excellent in a balance of hardness, strength, stretchability and wear resistance.SOLUTION: Moldings are obtained from powders. A material of this molding is a multicomponent alloy. The multicomponent 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, and V: 0.1 atom% or more and 20 atom% or less. The multicomponent alloy further contains O. A content of O is 20 ppmw or more and 1000 ppmw or less. The entropy ΔSmix of mixing of the multicomponent alloy is 1.30R or more. The valence electron concentration VEC of the alloy is greater than or equal to 7.84.SELECTED DRAWING: None
