Directed energy deposition (DED) has matured into an essential additive manufacturing (AM) branch. DED has been broadly implemented in the design and fabrication of novel materials. These include metals, ceramics, and composites. Successful DED operation requires a good understanding of many critical ...
Laser directed energy deposition (LDED) technology provides an opportunity to break through the size and geometry limitations of bulk metallic glasses (BMGs). However, the microcracks, induced by the huge thermal stress during the LDED process, seriously damage the mechanical properties of deposited ...
In the framework of Additive Manufacturing of metals, Directed Energy Deposition of steel powder over flat surfaces and edges has been investigated in this paper. The aims are the repair and overhaul of actual, worn-out, high price sensitive metal components. A full-factorial experimental plan has...
Laser-based directed energy deposition (L-DED) is a widely used additive manufacturing (AM) technique capable of creating free-standing 3-dimensional (3D) structures and coating/cladding an existing metallic component1,2. With this technique, a nickel-based superalloy-IN718 is amongst easily fabri...
