CEMENTED CARBIDE POWDERS FOR ADDITIVE MANUFACTURING
Cemented carbide powder compositions are provided for use in the production of various articles by one or more additive manufacturing techniques. In one aspect, a powder composition comprises sintered cemented carbide particles having at least a bimodal particle size distribution, wherein sintered cemented carbide particles of a first mode exhibit a D50 particle size of 25 μm to 50 μm, and sintered cemented carbide particles of a second mode exhibit a D50 of less than 10 μm, and the powder composition has an apparent density of 3.5 g/cm3 to 8 g/cm3.
