| Abstract Scope |
Although the consideration of directional and rapid aspects of solidification in fusion-based additive manufacturing (F-BAM) provides a straightforward rationale for a few observed microstructural phenomena and subsequent properties, these considerations are inadequate for functional gradation of the overall microstructural hierarchy and properties. In this talk, we report encouraging microstructural features, such as single crystal-like texture and spatially varying undercooling of solidifying phases in wire arc additive manufacturing (WAAM)-processed steels. Subsequently, we discuss the phenomena occurring during and post solidification that can affect the texture and phase evolution in WAAM. Results obtained from thermomechanical modeling that indicate the effect of phenomena occurring during and post solidification on texture evolution are also discussed. Implications of such compelling microstructural features for mechanical behavior are discussed with examples. Overall, the findings discussed in this talk will facilitate site specific tailoring of crystallographic texture, solidification behavior and mechanical behavior of WAAM processed steels. |
