Abstract Scope |
Aluminum alloys are utilized for aerospace, automotive, and other industrial applications with their ability to withstand extreme conditions. This work investigates additively manufactured aluminum metal matrix composites that are reinforced with boron carbide to explore the role of these inoculants on material strength and corresponding morphology. It is understood that inoculants refine the grains, but we aim to provide a statistical correlation between the microstructure and failure behavior. Electron backscatter diffraction (EBSD) is implemented to evaluate the microstructural characteristics and changes, such as grain size and orientation, in response to deformation under uniaxial tension for samples containing varying weight percentages of boron carbide. We then use transmission electron microscopy (TEM) to analyze the deformation processes leading to failure. Automating the data collection and analysis is another important aspect as we work to identify the characteristics which optimize the manufacturing and utility of these materials. |
