Effect of Deposition Sequence on Microstructure and Properties of 316L and Inconel 625 Bimetallic Structure by Wire Arc Additive Manufacturing

Wire arc additive manufacturing based on cold metal transfer was applied to deposit 316L and Inconel 625 bimetallic structures in this work. The effect of deposition sequence on the microstructure and properties of the bimetallic structure was emphatically studied. The results showed that with the increase in the number of deposition layers, the morphology of δ-ferrite in 316L changed from lath to skeleton, and the amount of Laves phase in...
