Abstract
An alloy member and a product using the same are provided. The alloy member includes elements Co, Cr, Fe, Ni, and Ti each in a range of 5 atom % or more to 35 atom % or less, Mo in a range exceeding 0 atom % and 8 atom % or less, and unavoidable impurities as a remainder. The alloy member includes a microcell structure with an average particle diameter of 10 μm or less at least in crystal grains of a surface layer part. A boundary part of the microcell structure has a dislocation having a surface density higher than that inside the microcell structure. Ultrafine particles having an average particle diameter of 50 nm or less are dispersed and precipitate at least inside the microcell structure.
