NI-BASED ALLOY MEMBER COMPRISING ADDITIVELY MANUFACTURED ARTICLE, METHOD FOR MANUFACTURING NI-BASED ALLOY MEMBER, AND PRODUCT USING NI-BASED ALLOY MEMBER

摘要

To provide an additively manufactured body including a Ni-Cr-Mo based alloy that is excellent in mechanical properties. An additively manufactured body of the present invention is a member including a Ni-based alloy that includes Ni at the largest content by a mass ratio, and Cr and Mo at second largest contents by a mass ratio; and includes segregation of Mo in at least a part of a crystal grain(s). This crystal grain(s) has columnar cell structures (CL), and preferably the segregation of Mo exists between adjacent cell structures. According to the additively manufactured body of the present invention, a tensile strength of 850 MPa or higher and an elongation of 50% or higher can be obtained.
