| Abstract Scope |
Site-specific microstructure control in metal additive manufacturing (AM) is a new paradigm aimed at producing parts with complex geometries which integrate multiple properties. In powder bed fusion technologies—such as selective laser melting (SLM)—microstructure control may be achieved by tailoring the solidification direction of the melt pool, layer by layer. In this work, we demonstrate this capability by varying the laser scanning angle during SLM to produce stainless steel samples with controlled crystallographic textures. The resulting microstructures range from quasi-single crystalline, to layers of controlled thickness with distinct and narrow grain orientation distribution. This strategy paves the way to a new generation of additively manufactured metals with optimized, site-specific properties to suit a wide range of applications. |
