“…12 (numbered arrows). Considering the results and matching them with previous studies 26 , 27 , the multi-material microstructure in the SS316L section mostly consists of austenite phase and a small amount of the delta ferrite phase (δ) in the intercellular regions (Fig. 15 a,b, respectively).…”

“…This type of microstructure is usually attributed to the additive manufacturing process itself since they are not continuous processes. Each layer is solidi ed during its material layer deposition, but also experiences partial melting and solidi cation steps with the subsequent layer deposition as it was reported in other research [9].…”

“…Referring to the DoA scheme (table S3 and Supplementary text B), the DoA value of the examined melt pool's cross-section shows a majority level, indicating that the temperature gradient and the composition dominate the grain growth. On the one hand, the grain growth along the gradient direction tends to form elongated columnar grains in the middle zone; on the other hand, the large interdiffusion of Fe causes an uneven solute distribution, further leading to a certain extent of constitutional supercooling [61], which is conducive to promoting the transition from columnar to equiaxed grains, as shown in the upper zone of the clad layer. Grain size statistics for clad layers of single tracks can illustrate differences in microstructural features.…”
