Composite member

Abstract

The present invention provides an alloy, an alloy powder, an alloy member, and a composite member which are excellent in corrosion resistance and wear resistance, have crack resistance, and are suitable for an additive manufacturing method and the like. An alloy and an alloy powder include, by mass %, Cr: 18 to 22%, Mo: 18 to 28%, Ta: 1.5 to 57%, C: 1.0 to 2.5%, Nb: 0 to 42%, Ti: 0 to 15%, V: 0 to 27%, Zr: 0 to 29%, and a remainder consisting of Ni and unavoidable impurities, where a molar ratio of (Ta+0.7Nb+Ti+0.6V+Zr)/C=0.5 to 1.5 is satisfied. An alloy member is an additively manufactured product or a cast having such a solidification structure, and the solidification structure is a dendrite-like crystal structure having a metal phase having a face-centered cubic structure and carbides.
