| Abstract Scope |
Laser powder bed fusion is an additive manufacturing technique that allows for the production of materials with complex geometries, desirable mechanical properties and composition. Aluminum’s wide solidification range in addition to the columnar grain growth make it a difficult material to print. The introduction of ceramic inoculants to the aluminum matrix via reactive additive manufacturing (RAM) improves the printability in addition to its mechanical properties. We investigate the failure behavior of aluminum 1000 reinforced with titanium diboride and titanium carbide inoculants. Employing ex situ tensile testing, scanning electron microscopy, transmission electron microscopy, and in situ digital image correlation combined with electron backscattered diffraction (DIC-EBSD), we aim to understand the role of the ceramic inoculants in the failure behavior of this material. Here, we present multiscale experimentation and characterization on four samples with different weight fractions of ceramic inoculants. |
