摘要： A method of fabricating a cemented carbide article by additive manufacturing, and a granular material are disclosed. A precursor material is provided that comprises granules, the granules comprising carbide grains and a binder comprising any of cobalt, nickel and iron. Each granule has a density of at least 99.5% of the theoretical density and the granules of the precursor material have a mean compressive strength of at least 40 megapascals (MPa). An additive manufacturing process is used to manufacture the article by building up successive layers of material derived from the precursor material.
