| Abstract Scope |
Metal additive manufacturing technologies like directed energy deposition have the possibility of fabricating components on the size scale of meters including valves, pumps, impellers, etc. that are challenging or difficult to source, especially when developing new systems or replacing obsolete components. Also, exploring convergent manufacturing strategies, like coupling AM with Powder Metallurgy techniques, can provide unique cost and/or performance opportunities for large-scale parts that demand much less production volume (number of parts). Keeping the above aspects in mind, the current effort scopes out various wire and blown-powder DED modalities to fabricate Hot Isostatic Pressure (HIP) cans. Processing-Structure-Property assessment of associated AM+PM parts in as-fabricated and post-HIPed states were conducted. Several smart manufacturing tools with state-of-the-art in situ monitoring setup were implemented for each of the DED modalities. This is extremely relevant towards the end goal of inspection and certification of large-scale advance manufactured parts for nuclear applications. |
