Thin wall deposition of IN625 using directed energy deposition
Journal of Manufacturing Processes, 2020Abstract Laser powder-blown directed energy deposition (DED) is widely used for small feature deposition ability and geometrical accuracy. The effects of process parameters, control, and toolpath strategies on geometry of the final product and mechanical properties have been investigated in many different parent geometries, however, deposition on an ...

Directed Energy Deposition Processes
2015Directed energy deposition (DED) processes enable the creation of parts by melting material as it is being deposited. Although this basic approach can work for polymers, ceramics, and metal matrix composites, it is predominantly used for metal powders. Thus, this technology is often referred to as “metal deposition” technology.

The influence of direct energy deposition on BWR stability
Annals of Nuclear Energy, 2001Abstract Direct energy deposition into the coolant of a BWR via high-energy γ s and neutrons is always neglected in reduced-order BWR dynamics models. The correctness of such a simple approach is investigated by comparing reactor stability predictions of the March–Leuba–Cacuci–Perez reduced-order model, with a model where direct heating has been ...
