摘要：

Laser-based Directed Energy Deposition (DED) is being used increasingly for printing functionally graded materials (FGMs). In the DED process, two metal powders are blown into the molten pool. The printed functionally gradient material has layered structures with the composition ratio in each layer changing gradually. We report an interesting molten pool swing phenomenon in the DED printing of the stainless steel 316L/Inconel 718 gradient material. It is found that the molten pool moves around periodically and its light intensity changes between bright and less bright in sequence in printing the layer of 75% SS316L and 25% IN718.(c) 2022 Published by Elsevier Ltd on behalf of Society of Manufacturing Engineers (SME).
