Abstract
Provided are a Ni—Cr—Mo-based alloy, a Ni—Cr—Mo-based alloy powder, a Ni—Cr—Mo-based alloy member, and a member that can be melted and solidified and have excellent corrosion resistance, wear resistance, and crack resistance. A Ni—Cr—Mo-based alloy member according to the present invention includes, by mass %, Cr: 18% to 22%, Mo: 18% to 39%, Ta: 1.5% to 2.5%, B: 1.0% to 2.5%, and a remainder consisting of Ni and unavoidable impurities, where 25≤Cr+(Mo/2B)<38 is satisfied, in which boride particles with a maximum particle size of 70 μm or less are dispersed and precipitated in a parent phase.
