3.3.1Directed energy deposition Directed energy depositionis a broadly employed3D printingtechnique for producing gradient-structured metals and alloys. This process utilizes an electric arc or laser to melt metals in the form of wires or powders[103–106]. This allows for precise control over the...
Direct energy deposition was used to obtain the carbides MxCyin carbon-fibers-reinforced Fe鈥揘i matrix composites. The direct energy deposition method has... A Gorunov - 《Progress in Additive Manufacturing》 被引量: 0发表: 2024年 Impact of Residual Surface Charges on Energy Coupling of Packed...
Here, we present directed energy deposition (DED) of wrought-like Al 5xxx AlMg alloy by Laser Engineered Net Shaping (LENS®). A transition from an Al 5083 gas atomized powder feedstock to Al 5754 characteristics of the as-deposited material due to selective evaporation of Mg was observed....
Machine-Aware Direct Energy Deposition ESPRIT provides a natural workflow for programming direct energy deposition machines. The machines may be dedicated additive machines or hybrid additive machines that also perform traditional subtractive machining. Using ESPRIT’s concept of machine awareness, a dig...
This study investigates the effect of wire arc direct energy deposition (WADED) of low-carbon steel on mild steel substrates, focusing on temperature distribution, distortion analysis, and the in situ addition of micropowders to enhance mechanical properties. Experimental and numerical analyses were con...

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 ...
