“…As they cool to the ductility dip temperature range, strain localization and an inherent reduction in ductility can precipitate cracking, as delineated in Zhang et al's study [81] examining cracking mechanisms in laser-melted Inconel 738 alloys (refer to Figure 5). Regarding the impetus for crack formation, based on the research by Guo et al [82] and Zhou et al [83], the genesis of cracking is closely correlated with residual stresses in additively manufactured components. Guo et al showed that tensile residual stresses can accelerate crack growth along the lamellar structure in 316L stainless steel produced by DED.…”

“…In turn, this approach helps minimize part distortion, lack of fusion defects, and the propensity for cracking in the fabricated component. Zhang et al [85] proposed an innovative in situ doping approach, whereby thin interlayers of Inconel 718 were deposited between Regarding the impetus for crack formation, based on the research by Guo et al [82] and Zhou et al [83], the genesis of cracking is closely correlated with residual stresses in additively manufactured components.

“…However, the detailed in-situ information about interrelationship of molten metal flow and porosity formation are limited due to the instantaneity of fusion welding process and opacity of metallic materials, when conventional metallographic methods are used to observe the melt pools and weld joints. Synchrotron X-ray imaging has recently become an important way to study the dynamic processes, such as melting and solidification, in the welding and additive manufacturing of metallic alloys [10][11][12][13][14][15][16]. Notably, data collected from real-time X-ray experiments is critical for developing IOP Publishing doi:10.1088/1757-899X/1274/1/012011 2 physically accurate simulation models of dynamic melt pools [17,18].…”
