摘要： A method of manufacturing a ferrous alloy article is disclosed and includes the steps of melting a ferrous alloy composition into a liquid, atomizing and solidifying the liquid into powder particles, removing oxygen from surfaces of the powder particles to reduce a bulk oxygen content to approximately ≤20 ppm, and consolidating the powder particles into a monolithic article.
