Abstract Scope |
Metal additive manufacturing (AM) evolved over the last decade to serve the current manufacturing needs. However, the tradeoff between cost, lead time, part complexity, size, and scalability for parts produced via AM versus powder metallurgy (PM) is still a point of contention. This talk demonstrates the feasibility of a combined AM + PM approach to fabricate metal parts which benefit from the intrinsic advantages of both AM and PM. Powders of 316L stainless steel (SS) were poured into canisters fabricated via (1) conventional extrusion, (2) laser powder bed fusion (LPBF), and (3) blown powder directed energy deposition (BP-DED) and then degassed and subjected to HIPing. Post-HIP specimens were characterized for microstructure, physical, and mechanical properties. This study provides a preliminary overview of the opportunities and challenges associated with the AM + PM approach and offers valuable insights that can further guide the fabrication of complex, large-scale metal components. |
