NI-BASED ALLOY MEMBER COMPRISING ADDITIVELY MANUFACTURED ARTICLE, METHOD FOR MANUFACTURING NI-BASED ALLOY MEMBER, AND PRODUCT USING NI-BASED ALLOY MEMBER
NI-BASED ALLOY MEMBER COMPRISING ADDITIVELY MANUFACTURED ARTICLE, METHOD FOR MANUFACTURING NI-BASED ALLOY MEMBER, AND PRODUCT USING NI-BASED ALLOY MEMBER
Provided is an additively manufactured article having excellent mechanical properties and comprising a Ni-Cr-Mo based alloy. The additively manufactured article according to present invention is a member comprising a Ni-based alloy in which, in terms of the mass ratio, the Ni content is the highest, followed by the Cr content and the Mo content, and Mo segregation occurs in at least a portion of crystal grains. The crystal grains have a columnar cellular structure (CL), and Mo segregation preferably occurs between adjacent cellular structures. The additively manufactured article of the present invention can achieve a tensile strength of 850 MPa or more and an elongation of 50% or more.
