Abstract Scope |
Aluminium alloys reinforced with ceramic particles have been extensively investigated for automotive applications. Presently, growing attention has been drawn to their application within electric vehicles due to their high strength and lightweight. Among various reinforcements, titanium carbide (TiC) is of particular interest due to its superior hardness, high wear resistance, excellent elastic modulus, and relatively low coefficients of thermal expansion. This study aims to explore the effect of nano-to-submicron-sized (<2 µm) TiC particles on the mechanical properties of a commercial 6xxx aluminium alloy by incorporating Al-50TiC master powders. Stir casting with the aid of ultrasound processing was applied to facilitate the mixing and dispersion of TiC particles. Composites with additions of 0.5, 1, 2, and 5wt% TiC were prepared by gravity casting using a permanent steel mould. The effect of the TiC particles on the microstructure, with respect to casting defects, particle distributions, and particle/matrix bonding has been investigated. |
