Abstract Scope |
Wire-based Direct Energy Deposition (W-DED) processes are attractive additive manufacturing (AM) processes to replace conventional casting and forging methods of structural alloys due to their net shaping capabilities and low machining waste. Common W-DED processes used to manufacture these alloys include wire arc additive manufacturing (WAAM), electron beam additive manufacturing (EBAM), and laser hot-wire additive manufacturing (LHW). Understanding the process-structure-property-performance relationships of W-DED components is important as material produced by W-DED processes often exhibits large columnar grains which can induce severe anisotropy in the associated mechanical properties. Work has been done to understand the microstructural features of material from multiple W-DED processes. Additional exploration has been done using both custom post-process heat treatments and in-situ methods to manipulate the as-built microstructures of W-DED components. Mechanical testing and microstructural analysis were utilized to understand the effects of these processing methods on the deposited material.
