A novel directed energy deposition-arc method of deposition layer without focused thermal energy heating: droplet transfer, morphology and microstructure

Journal of Materials Research and Technology, 2023
Additive manufacturing (AM) of metal usually forms columnar grains along the building direction due to the focused thermal energy directly heating the deposition layer to easily obtain an obvious temperature gradient.
