“…Ji et al's investigation [105] into the influence of UA amplitudes on the microstructure and mechanical attributes of steel alloy fabricated via arc DED revealed that an increase in ultrasonic amplitude significantly alters the microstructure and simultaneously improves the mechanical properties of the fabricated ER70S-6 steel alloy. Commencing from an amplitude of 0 µm, where coarse columnar grains predominate, an increment to 5 µm instigated a localized refinement in the deposition layer's central region.…”

Directed Energy Deposition (DED), a branch of AM processes, has emerged as a significant technique for fabricating large metal components in sectors such as aerospace, automotive, and healthcare. DED is characterized by its high deposition rate and scalability, which stand out among other AM processes. However, it encounters critical issues such as residual stresses, distortion, porosity, and rough surfaces resulting from rapid melting and solidification. As a novel advancement, Ultrasonic-Assisted Directed Energy Deposition (UA-DED) integrates ultrasonic oscillations into DED aimed at addressing these challenges. Herein, the latest research related to the UA-DED process and the current major challenges of the DED process, residual stresses, porosity, and crack defects are critically reviewed. Subsequently, the paper also details the working principle and system components of UA-DED technology and reviews the material improvement by introducing UA into the DED process, grain, porosity, tensile properties, and deposition defects. The most critical optimization methods of process parameter variables for UA and the different material interaction mechanisms between UA and DED processes are identified and discussed in detail. Finally, the perspectives on the research gap and potential future developments in UA-DED are also discussed.

“…In the welding field, ultrasound is being applied and researched gradually. Feilong Ji et al [29] coupled ultrasonic energy with the arc deposition process to study the effect of ultrasonic intensity on the microstructure and mechanical properties of ER70S-6 steel alloy during the direct energy deposition arc (DED-Arc) process. To analyze the propagation and vibration distribution of ultrasonic waves in the matrix, numerical simulation methods were employed.…”

The microstructure and mechanical properties of ultra-high-strength steel weld joints were examined for the effect of ultrasonic treatment. ER120S-G welding wire is necessary for welding 4 mm thick ultra-high-strength steel. After that, the weld toe region underwent different parameters of the ultrasonic stress relief process. As a means of surface treatment for weld seams, noticeable grain refinement and the formation of a fine-grained layer were observed in the weld toe region after ultrasonic treatment. The blind hole method was used to measure residual stresses in the weld seam, which indicated a transition from tensile stress to compressive stress in the treated portion of the joint. Different ultrasonic treatment processes resulted in a significant increase in hardness values near the weld toe region during hardness testing. The hardness of the weld joint that was treated with ultrasound increased initially but then stabilized after increasing the frequency. The ultrasound-treated joints showed a significant improvement in both tensile strength and fracture elongation, as demonstrated in the tensile tests.
