Abstract Scope |
Al-SiC composites are important materials for high strength, high stiffness, and lightweight applications. The problem with using X-ray microscopy to study Al-SiC composites is that the densities of Al and SiC are very similar. In this study, we used a novel dual-energy X-ray Computed Tomography (DE-XCT) approach to segment the different phases of a functionally graded Al-SiC composite fabricated by spark plasma sintering. Using the DE-XCT data and 2D histogram-based annotated segmentation, we segmented the different phases of the composite and performed watershed analysis on the SiC phase to quantify the size, shape, orientation, and spatial distribution of the SiC particles in the composite. The segmentation and watershed analyses showed that the SiC particles are homogeneously distributed in the Al matrix and appear to have a preferred orientation. The combined use of DE-XCT scans and watershed analysis allowed us to gain important insights into the microstructure of the Al-SiC composite. |
