Copper‐Based Crystalline‐Metallic Glass Composite Thin Films: A Novel Material with Enhanced Strength and Thermally Stable Nanotwins

open access: yesAdvanced Functional Materials, EarlyView.
A Cu‐based crystal‐glass composite with high‐density twins is identified by a fast screening technique using combinatorial sputtering together with XRD and nanoindentation mapping. This bamboo‐like structure demonstrates homogenous plastic flow and retains high strength during in situ high temperature tests, up to 1 GPa at 550°C, owing to those ...

Magnetically assisted directed energy deposition

Journal of Materials Processing Technology, 2021
Abstract Poor powder catchment efficiency, is a limiting factor in the adoption of Directed Energy Deposition for the processing of expensive materials, complex shapes and for the sake of energy efficiency. This study demonstrates a novel approach to improve powder catchment efficiency using a magnetic field to direct ferritic steel powder during ...

Directed Energy deposition

2020
Directed Energy Deposition (DED) is a method for melting material as it is being deposited layer-by-layer. Material in wire or powder form is delivered along with the energy required to melt it. Although it has been shown that a number of material types can be processed this way, DED is almost exclusively applied to metals in both research and ...

Directed-Energy Deposition

2022
AbstractThis article focuses on the directed-energy deposition (DED) additive manufacturing (AM) technique of biomedical alloys. First, it provides an overview of the DED process. This is followed by a section describing the design and development of the multiphysics computational modeling of the layer-by-layer fusion-based DED process.

Directed energy deposition of molybdenum

International Journal of Refractory Metals and Hard Materials, 2019
Abstract Two directed energy deposition processes were evaluated for additive manufacturing of molybdenum. First, a laser-based process was used to deposit plasma spheroidized molybdenum powder. The effects of laser power, substrate temperature, and substrate composition on deposition quality were explored.
