Abstract
The present invention relates to an additive manufacturing powder material including Fe alloy particles each having an oxide film on a surface thereof, in which the Fe alloy particles satisfy d≤15 and I/d≤0.025, where d [nm] represents a thickness of the oxide film, and a peak intensity ratio I represents an intensity ratio IB/IA of a peak B in a region B of a Raman shift of 1,309 to 1,329 cmto a peak A in a region A of a Raman shift of 657.5 to 677.5 cmin a Raman spectrum.
