Title:
積層造形用Ｎｉ基超合金粉末
Document Type and Number:
Japanese Patent JP6499546
Kind Code:
B2
Abstract:
The present invention provides a Ni-based superalloy powder for use in additive manufacturing, comprising, on the basis of mass %: 0 to 0.2% C; 0.05 to 1.0% Si; 0.05 to 1.0% Mn; 10.0 to 25.0% Cr; 0.01 to 10% Fe; 0.1 to 8.0% Al; 0.1 to 8.0% Ti; 0.002% or less S and/or 0.10% or less N; and the balance being Ni and incidental impurities. The Ni-based superalloy powder of the invention allows production of a good sintered body even during sintering by a rapid melting-rapid solidification process, such as additive manufacturing.
