  • Binder jetting and supersolidus sintering of ferrous powder metal components
    Patent number: 11465209
    Abstract: A densified, high-strength metallic component is manufactured by: binder jet additive manufacture (BJAM) printing a powder blend to form a printed part; and super solidus sintering the printed part to form the metallic component, which may then be heat treated. The powder blend comprises a blend of water atomized base iron powder and a high-carbon master ferroalloy powder. The high-carbon ferroalloy powder introduces high concentrations of carbon into a powder blend that is readily BJAM printable.
