| Abstract Scope |
We present an analysis on aluminum alloys reinforced by ceramic particles formed in situ during laser powder bed fusion (PBF-LB) through a process called reactive additive manufacturing (RAM). Here, aluminum powders are mixed with titanium and boron carbide powders to form an aluminum matrix reinforced by TiB2 and TiC ceramic particles in fractions between 0-10% following the PBF-LB process. The strength-ductility tradeoff and corresponding failure mechanisms in these composites with varying fractions of ceramic particles is studied. Using scanning electron microscopy and transmission electron microscopy imaging in addition to electron backscatter diffraction, we conduct a statistical analysis of the particle and grain size distributions for each composite. We perform uniaxial tensile testing to observe the strength-ductility properties, and perform in situ tensile testing inside the scanning electron microscope to analyze the crack initiation sites and mechanisms leading to failure. |
