Abstract Scope |
The demand for light aluminium alloys and composite components is increasing in automotive and aerospace applications. Aluminium based metal matrix composites (MMC) having particle reinforcements have been found to be attractive primarily due to the properties of high specific strength and stiffness. In this study, Al-4.5Cu-5TiB2 composite is prepared by in-situ liquid metallurgy route using salts of K2TiF6 and KBF4 whose reaction produced TiB2 particles. Mushy state rolling/forging is used to reduce defects formation and to disperse of particles in the composite. Understanding the defect formation and particle distribution is essential for improving the composite properties. X-ray computed tomography (XCT) is a non-destructive technique which enables 3D visualization of microstructural features such as porosity and particles distribution in the alloy composites. Quantification of porosity and particle distribution in semi solid processed Al-Cu-TiB2 composites is presented and discussed. |
