NET-SHAPE OR NEAR-NET SHAPE POWDER METAL COMPONENTS AND METHODS FOR PRODUCING THE SAME

摘要

The present disclosure relates to net-shape or near-net shape articles of manufacture and methods for producing the same. For example, a method for manufacturing net-shape or near-net shape metallic article includes the steps of: forming, using an additive manufacturing process, a metal can comprising a hollow interior portion, filling the hollow interior portion with a metal powder, and subjecting the metal can filled with the metal powder to a hot isostatic pressing (HIP) process to densify the metal powder. As another example, a net-shape or near-net shape metallic article of manufacture includes a metallic outer shell portion having a layer-by-layer fused microstructure that exhibits anisotropic mechanical and physical properties and a metallic inner core portion having a pressure-densified microstructure that exhibits isotropic mechanical and physical properties.
