| Abstract Scope |
Fe-bearing intermetallic particles (Fe-IMPs) are formed during casting of aluminum alloys. These particles can affect the mechanical properties and formability of the alloys in part due to their complex interconnected morphologies. In this work, X-ray Computed Tomography (XCT) was used to capture the 3D morphology of Fe-IMPs in the Al-Mg based alloys with high Fe contents. The differences in morphologies of the Fe-IMCs in both alloys were quantified using a new 3D morphological descriptor - the particle-to-convex hull volume ratio. The morphology data of the Fe-IMPs was correlated with Energy Dispersive Spectroscopy (EDS) measurements, and nano-indentation data to develop a coherent understanding of Fe-IMP particle evolution during thermo-mechanical processing. |
